The flag of the Lithuanian SSR was first adopted by the Lithuanian SSR in 1918, which was a plain red flag. After the Lithuanian SSR was established again in 1940, the flag was a red flag with the national name and a hammer and sickle in the upper canton. The flag in use from 1953 to 1988 was a red flag with the golden hammer and sickle and a gold-bordered red star in its upper canton with a white thin stripe and green thick band on the bottom.
