Bolshoi Tyuters (Russian: Большой Тютерс; Finnish: Tytärsaari; Estonian: Suur Tütarsaar; Swedish: Tyterskär) is an island in the Gulf of Finland of the Baltic Sea, located 75 km (47 mi) away from the coast of Finland. The island is part of the Leningrad Oblast, Russia. The area is approximately 8.3 km2 (3.2 sq mi). The island was populated by Finns from the 16th century to 1939.
