The Don't Ask, Don't Tell Repeal Act of 2010 (H.R. 2965, S. 4023) is a landmark United States federal statute enacted in December 2010 that established a process for ending the Don't ask, don't tell (DADT) policy (10 U.S.C. ยง 654), thus allowing gay, lesbian, and bisexual people to serve openly in the United States Armed Forces. It ended the policy in place since 1993 that allowed them to serve only if they kept their sexual orientation secret and the military did not learn of their sexual orientation, which was controversial.

The Act established a process for ending the "Don't ask, don't tell" policy. According to the Congressional Research Service, the Act:[3]

The repeal of DADT did not alter the language of Article 125 of the Uniform Code of Military Justice, which banned sodomy by service members. This prohibition was removed upon enactment of the National Defense Authorization Act for Fiscal Year 2014.[30]
