Leonid Bykov (Ukrainian: Леонід Федорович Биков, Russian: Леонид Фёдорович Быков, 11 December 1928 in Znamenske, Donetsk Oblast of Ukraine, USSR - 11 April 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.
In 1994, the International Astronomical Union named a minor planet after him, (4682) Bykov.
