Leonid Bykov (Ukrainian: Леонід Федорович Биков, Russian: Леонид Фёдорович Быков, December 12, 1928 in Znamenske, Donetsk Oblast of Ukraine, USSR - April 11, 1979 in Kiev Oblast of Ukraine, USSR) was a Soviet-Ukrainian actor, film director, and script writer.

Bykov contributed to several Soviet World War II films (that all reached iconic status) and significantly delivered to the cliche image of a Soviet Ukrainian.

Bykov was killed in a car accident in 1979 on the highway from Minsk to Kiev.
