The Act of Declaration of Independence of Ukraine  (Ukrainian: Акт проголошення незалежності України) was received by the Ukrainian parliament on 24 August 1991. The Act re-established Ukraine’s state independence. The act was introduced in the aftermath of the 19 August coup attempt, when hardline Soviet Union Communist leaders sought to regain central Communist Party control over the USSR.

In response (within a stressful 11-hour extraordinary session), the Supreme Soviet (parliament) of the Ukrainian SSR, overwhelmingly approved the Declaration Act in a special Saturday session.
