Uusimaa was a gunboat that served in the Finnish Navy during World War II. She was built in 1917. As the ship had changed hands many times during the turbulent last years of World War I she had been renamed many times: In Russian service, she was called Golub, later, in German service, her name was Beo. Finally the Germans handed her over to the Finns in 1920, who renamed her Uusimaa. After World War II, she served as a trawler in the Baltic Sea. She was scrapped in 1953.
