Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The accompanying unaudited condensed consolidated financial statements of Dollar Tree, Inc. and its wholly-owned subsidiaries (the "Company") have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and are presented in accordance with the requirements of Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete consolidated financial statements. The unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto and Management's Discussion and Analysis of Financial Condition and Results of Operations for the year ended January 28, 2017 contained in the Company's Annual Report on Form 10-K filed March 28, 2017. The results of operations for the 13 weeks ended April 29, 2017 are not necessarily indicative of the results to be expected for the entire fiscal year ending February 3, 2018. In the Company's opinion, the unaudited condensed consolidated financial statements included herein contain all adjustments (including those of a normal recurring nature) considered necessary for a fair presentation of its financial position as of April 29, 2017 and April 30, 2016 and the results of its operations and cash flows for the periods presented. The January 28, 2017 balance sheet information was derived from the audited consolidated financial statements as of that date. In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers." This update will replace existing revenue recognition guidance in GAAP and requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. In July 2015, the FASB deferred the effective date of the new standard to interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted, but not before the original effective date for public business entities (interim and annual reporting periods beginning after December 15, 2016). ASU 2014-09 permits the use of either the retrospective or cumulative effect transition method. The Company does not expect the adoption of this pronouncement to have a material impact on its financial statements. In February 2016, the FASB issued ASU No. 2016-02, "Leases." This update will replace existing lease guidance in GAAP and will require lessees to recognize lease assets and lease liabilities on the balance sheet for all leases and disclose key information about leasing arrangements, such as information about variable lease payments and options to renew and terminate leases. When implemented, lessees and lessors will be required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The update is effective for interim and annual reporting periods beginning after December 15, 2018. Early adoption is permitted. The Company has engaged a third party to assist in its preparation for implementation and its evaluation of the impact of the new pronouncement on its consolidated financial statements. The Company expects the adoption of this pronouncement to result in a material increase in the assets and liabilities on its consolidated balance sheets and to not have a material impact on its consolidated income statements.

LONG-TERM DEBT	3 Months Ended

Debt Disclosure [Abstract]
LONG-TERM DEBT	LONG-TERM DEBT Acquisition Notes The Company's $750.0 million aggregate principal amount of 5.25% senior notes due 2020 (the "2020 Notes") and $2.5 billion aggregate principal amount of 5.75% senior notes due 2023 (the "2023 Notes," and together with the 2020 Notes, the "Acquisition Notes") were issued pursuant to indentures, which contain covenants that, among other things, limit the ability of the Company to declare or pay dividends. The restriction in the indentures on the Company's ability to pay dividends is subject to certain significant exceptions, including an exception that permits the Company to pay dividends and make other distributions regardless of dollar amount so long as, after giving pro forma effect thereto, the Company would have a consolidated total net leverage ratio, as defined under the indentures, no greater than 3.50 to 1.00. As of April 29, 2017, the Company's consolidated total net leverage ratio, as defined in the indentures, was below 3.50 to 1.00. So long as the Company's consolidated total net leverage ratio remains below 3.50 to 1.00, the indentures do not restrict the ability of the Company to pay dividends. Credit Facility and Term Loans The Company's New Senior Secured Credit Facilities, consisting of its $1.25 billion revolving credit facility and term loan facilities, contain covenants that, among other things, limit the ability of the Company to declare or pay dividends. The restriction in the New Senior Secured Credit Facilities on the Company's ability to pay dividends is subject to certain significant exceptions, including an exception that permits the Company to pay dividends and make other restricted payments regardless of dollar amount so long as, after giving pro forma effect thereto, the Company would have a consolidated total net leverage ratio, as defined under the New Senior Secured Credit Facilities, no greater than 3.50 to 1.00. As of April 29, 2017, the Company's consolidated total net leverage ratio, as defined in the New Senior Secured Credit Facilities, was below 3.50 to 1.00. So long as the Company's consolidated total net leverage ratio remains below 3.50 to 1.00, the New Senior Secured Credit Facilities do not restrict the ability of the Company to pay dividends. Debt Covenants As of April 29, 2017, the Company was in compliance with its debt covenants.

LEGAL PROCEEDINGS	3 Months Ended
	Apr. 29, 2017
Commitments and Contingencies Disclosure [Abstract]
LEGAL PROCEEDINGS	LEGAL PROCEEDINGS The Company is a defendant in legal proceedings including those described below and will vigorously defend itself in these matters. The Company does not believe that any of these matters will, individually or in the aggregate, have a material effect on its business or financial condition. The Company cannot give assurance, however, that one or more of these matters will not have a material effect on its results of operations for the quarter or year in which they are resolved. The Company assesses its legal proceedings and reserves are established if a loss is probable and the amount of such loss can be reasonably estimated. Many if not substantially all of the contingencies described below are subject to significant uncertainties and, therefore, determining the likelihood of a loss and the measurement of any loss can be complex and subject to judgment. With respect to legal proceedings where the Company has determined that a loss is reasonably possible but not probable, the Company is unable to estimate the amount or range of the reasonably possible loss due to the inherent difficulty of predicting the outcome of and uncertainties regarding legal proceedings. The Company’s assessments are based on estimates and assumptions that have been deemed reasonable by management, but that may prove to be incomplete or inaccurate, and unanticipated events and circumstances may occur that might cause the Company to change those estimates and assumptions. Management’s assessment of legal proceedings could change because of future determinations or the discovery of facts which are not presently known. Accordingly, the ultimate costs of resolving these proceedings may be substantially higher or lower than currently estimated. Dollar Tree Active Matters In April 2015, a distribution center employee filed a class action in California state court with allegations concerning wages, meal and rest breaks, recovery periods, wage statements and timely termination pay. The employee filed an amended complaint in which he abandoned his attempt to certify a nation-wide class of non-exempt distribution center employees for alleged improper calculation of overtime compensation. The Company removed this lawsuit to federal court. The court is now considering the employee’s motion to certify the case as a state-wide class action. In April 2015, a former store manager filed a class action along with Private Attorney General Act ("PAGA") claims in California state court alleging store managers were improperly classified as exempt employees and, among other things on behalf of all California store employees, did not receive overtime compensation and meal and rest periods. The former employee also brought class action claims asserting the Company failed to make wage statements readily available to employees who did not receive paper checks. The Company removed the case to federal court where the Court denied certification of the classification issue and related claims but has not ruled on the PAGA claims. The Court did certify a wage statement class. In April 2016, the Company was served with a putative class action in Florida state court brought by a former store employee asserting the Company violated the Fair Credit Reporting Act in the way it handled background checks. Specifically, the former employee alleged the Company used disclosure forms that did not meet the statute’s requirements and failed to provide notices accompanied by background reports prior to taking adverse actions against prospective and existing employees based on information in the background reports. The plaintiff is seeking statutory damages of $100 to $1,000 per violation. In April 2016, a former store manager filed a lawsuit in California state court alleging individual claims of pregnancy and disability discrimination in addition to asserting PAGA claims on behalf of herself and other store managers alleging they were improperly classified as exempt and therefore, among other things, did not receive overtime compensation and meal and rest periods. The classification claims have been stayed pending the outcome of other lawsuits which were previously filed alleging similar PAGA claims. In July 2016, a former non-exempt sales associate filed in federal court in Arkansas a putative nationwide collective action alleging the Company forced sales associates and assistant store managers to work off the clock while clocked out for meal breaks and, as a result, underpaid regular and overtime pay. In September 2016, the court granted the Company’s motion to compel arbitration. To date, the former associate has not initiated any arbitration proceedings. In March 2017, a former store manager filed suit in a state court in Florida, seeking to represent a collective, alleging failure to pay non-exempt employees minimum wage for all time worked and overtime in violation of the Fair Labor Standards Act, and, individually, alleging race discrimination and retaliation in violation of federal and state civil rights laws. Pursuant to Court order, the case has been sent to arbitration. Family Dollar Active Matters In 2008, a complaint was filed alleging discriminatory practices with respect to the pay of Family Dollar's female store managers. Among other things, the plaintiffs seek recovery of back pay, monetary and punitive remedies, interest, attorneys' fees, and equitable relief. In June 2016, the United States District Court in North Carolina ordered that the case be continued for merits discovery. The court also certified the case as a class action of approximately 30,000 current and former female store managers employed as far back as July 2002. A preliminary settlement has been reached in this case and has been properly recorded by the Company. Other aspects of the settlement agreement are still being finalized. In 2014, a putative class action was filed in a California Federal Court by a former employee alleging that the Company had a policy of requiring employee bag checks while the employees were not clocked in for work. As a result of those actions, the employee alleges the Company violated California law by failing to provide meal periods and rest breaks, failing to pay regular and overtime wages for work performed off the clock, failing to provide accurate wage statements, failing to timely pay all final wages and by engaging in unfair competition. He has also alleged PAGA claims. The former employee dismissed his individual claims after the court ruled that the claims were subject to arbitration. The court ruled that the PAGA claims may proceed. In January 2017, a customer filed a class action in federal court in Illinois alleging the Company violated various state consumer fraud laws as well as express and implied warranties by selling a product that purported to contain aloe when it did not. The requested class is limited to the state of Illinois. The Company believes that it is fully indemnified by the entities that supplied it with the product. Family Dollar Resolved Matters In 2015, former employees filed a nationwide class action in federal court in Connecticut alleging the Company had violated ERISA by overcharging employees who purchased supplemental life insurance through a Company sponsored plan. In March 2016, the district court dismissed the lawsuit. The Second Circuit Court of Appeals affirmed the dismissal of the lawsuit.

Under the transition services agreement, the Company provides merchandise and services and the buyer reimburses the Company. In the first quarter of 2017, the Company evaluated the collectability of its divestiture-related receivable. Based on information available, the Company determined that the outstanding balance of $50.9 million was not recoverable and recorded an impairment charge to write down the receivable to zero. The charge is recorded as “Receivable impairment” in the accompanying condensed consolidated income statements.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS As required, financial assets and liabilities are classified in the fair value hierarchy in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company's assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels. The following table sets forth the Company's financial assets and liabilities that are disclosed at fair value on a recurring basis: (in millions)   April 29, 2017   January 28, 2017   April 30, 2016 Level 1             Short-term investments   $ 4.0   $ 4.0   $ 4.0 Long-term debt - Secured Senior Notes and Acquisition Notes   3,745.0   3,740.3   3,759.6 Level 2             Long-term debt - term loans   2,817.7   2,828.2   3,890.3 The Company's cash and cash equivalents are valued at cost, which approximates fair value, due to the short-term maturities of these instruments. The fair values of the Company's Secured Senior Notes and Acquisition Notes were determined using Level 1 inputs as quoted prices in active markets for identical assets or liabilities are available. The fair values of the Company's term loans were determined using Level 2 inputs as quoted prices are readily available from pricing services, but the prices are not published. The carrying values of the Company's Tranche A Revolving Credit Facility at April 29, 2017 and January 28, 2017 and the Company's Revolving Credit Facility at April 30, 2016, approximated their fair values because the interest rates vary with market interest rates. Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the assets and liabilities are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (e.g., when there is evidence of impairment). The Company did not record any significant impairment charges during the 13 weeks ended April 29, 2017.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION The Company's stock-based compensation expense primarily includes the fair value of restricted stock units (RSUs) and employees' purchase rights under the Company's Employee Stock Purchase Plan. Stock-based compensation expense was $27.6 million and $24.8 million during the 13 weeks ended April 29, 2017 and April 30, 2016, respectively. The Company granted approximately 0.5 million service-based RSUs from the Omnibus Incentive Plan (Omnibus Plan) to employees and officers in the 13 weeks ended April 29, 2017. The estimated $41.5 million fair value of these RSUs is being expensed ratably over the three-year vesting periods, or shorter periods based on the retirement eligibility of certain grantees. The fair value was determined using the Company's closing stock price on the date of grant. The Company recognized $5.6 million of expense related to these RSUs during the 13 weeks ended April 29, 2017. In the 13 weeks ended April 29, 2017, the Company granted 0.2 million RSUs with a fair value of $18.4 million from the Omnibus Plan to certain officers of the Company, contingent on the Company meeting certain performance targets in fiscal 2017. If the Company meets these performance targets in fiscal 2017, the RSUs will vest ratably over three years. The estimated fair value of these RSUs is being expensed ratably over the three-year vesting periods, or shorter periods based on the retirement eligibility of certain grantees. The Company recognized $10.7 million of expense related to these RSUs in the 13 weeks ended April 29, 2017. In the 13 weeks ended April 29, 2017, the Company granted RSUs with a fair value of $4.1 million from the Omnibus Plan to certain officers of the Company, contingent on the Company meeting certain performance targets for the period beginning on January 29, 2017 and ending on February 1, 2020. Provided the vesting conditions are satisfied, the awards will vest at the end of the performance period. The estimated fair value of these RSUs is being expensed ratably over the three-year vesting period, or shorter periods based on the retirement eligibility of certain grantees. The Company recognized $1.7 million of expense related to these RSUs in the 13 weeks ended April 29, 2017. The Company recognized $8.3 million of expense related to RSUs granted prior to fiscal 2017 in the 13 weeks ended April 29, 2017. For the 13 weeks ended April 30, 2016, the Company recognized $8.1 million of expense related to these RSU's. The Company recognized $0.1 million of expense related to options granted prior to fiscal 2017 in the 13 weeks ended April 29, 2017. In the 13 weeks ended April 29, 2017, approximately 0.6 million RSUs vested and approximately 0.4 million shares, net of taxes, were issued. During the 13 weeks ended April 30, 2016, approximately 0.6 million RSUs vested and approximately 0.4 million shares, net of taxes, were issued. In connection with the Family Dollar acquisition, the Company converted approximately 1.5 million Family Dollar vested and unvested options into equivalent options to purchase Dollar Tree Common Stock at the date of the acquisition and recognized $0.4 million of expense related to these options during the 13 weeks ended April 29, 2017. The Company recognized $0.7 million of expense related to these options during the 13 weeks ended April 30, 2016.

The Family Dollar segment consists of the Company's operations under the "Family Dollar" brand, 11 distribution centers and a Store Support Center in Matthews, North Carolina. The Company measures the results of its segments using, among other measures, each segment's net sales, gross profit and operating income.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
New Accounting Pronouncements	In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers." This update will replace existing revenue recognition guidance in GAAP and requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. In July 2015, the FASB deferred the effective date of the new standard to interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted, but not before the original effective date for public business entities (interim and annual reporting periods beginning after December 15, 2016). ASU 2014-09 permits the use of either the retrospective or cumulative effect transition method. The Company does not expect the adoption of this pronouncement to have a material impact on its financial statements. In February 2016, the FASB issued ASU No. 2016-02, "Leases." This update will replace existing lease guidance in GAAP and will require lessees to recognize lease assets and lease liabilities on the balance sheet for all leases and disclose key information about leasing arrangements, such as information about variable lease payments and options to renew and terminate leases. When implemented, lessees and lessors will be required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The update is effective for interim and annual reporting periods beginning after December 15, 2018. Early adoption is permitted. The Company has engaged a third party to assist in its preparation for implementation and its evaluation of the impact of the new pronouncement on its consolidated financial statements. The Company expects the adoption of this pronouncement to result in a material increase in the assets and liabilities on its consolidated balance sheets and to not have a material impact on its consolidated income statements.
