The flag of the Latvian Soviet Socialist Republic flag shows a yellow hammer and sickle and outlined star on a red field above rippling water at the bottom, and was adopted by the (former) Latvian Soviet Socialist Republic on January 17, 1953.

Prior to this, from August 25, 1940, the flag was red with the gold hammer and sickle in the top-left corner, with the Latin characters LPSR (Latvijas Padomju Sociālistiskā Republika) above them in gold in a serif font.

The Soviet-era flag was officially replaced on February 27, 1990, when the national Flag of Latvia was reintroduced (while remained legally as a Soviet republic until September 6, 1991), and its use at public events is now banned.
