The Act of the Re-Establishment of the State of Lithuania or Act of March 11 (Lithuanian: Aktas dėl Lietuvos nepriklausomos valstybės atstatymo) was an independence declaration by the Lithuanian Soviet Socialist Republic adopted on March 11, 1990. Signed by all members of the Supreme Council of the Republic of Lithuania, the act emphasized restoration and legal continuity of the interwar Lithuania, which was occupied by the Soviet Union and lost independence in June 1940. It was the first time that a soviet socialist republic declared independence from the collapsing Soviet Union.
