The Council of Ministers of the Lithuanian SSR (Lithuanian: Lietuvos TSR Ministrų Taryba) or Council of People's Commissars in 1940–46 (Lithuanian: Lietuvos TSR Liaudies Komisarų Taryba) was the cabinet (executive branch) of the Lithuanian SSR, one of the republics of the Soviet Union. Its structure and functions were modeled after the Council of People's Commissars and Council of Ministers of the Soviet Union. The Council consisted of a chairman, first vice-chairman, vice-chairmen, ministers, and chairmen of state committees. The council's chairman was equivalent to a prime minister and was second in rank after the First Secretary of the Communist Party of Lithuania.[1]
