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.

When Lithuanian SSR was established again as a republic of the USSR, it adopted a new national flag on 30 July 1940.

The flag was red with the Latin characters LIETUVOS TSR (Lithuanian SSR in the Lithuanian language) in gold sans-serif typeface in the upper canton, and a gold hammer and sickle below the text.

The Supreme Soviet of the Lithuanian SSR, inspired by pro-independence Sąjūdis, amended the constitution and adopted the tricolour flag of Lithuania that was used during the interwar years.
