Leonid Kinskey (April 18, 1903 – September 8, 1998) was a Russian-born movie and television actor who enjoyed a long career. Kinskey is best known for his role as Sascha in the film Casablanca (1942).

Kinskey was born in St. Petersburg, Russia. He fled the Russian Revolution and acted on stage in Europe and South America before arriving in New York City in 1921. He joined the road production of Al Jolson's musical Wonder Bar, before making his first film appearance, in the 1932 Trouble in Paradise. His looks and accent helped him land supporting roles in numerous movies, including Duck Soup and Nothing Sacred, and on television, well into the 1960s. It is said that he got perhaps his best-known role, Sascha in Casablanca, because he was a drinking buddy of star Humphrey Bogart. Kinskey was in the pilot episode for Hogan's Heroes, but turned down a regular role in the series because he thought the subject matter was being taken too lightly.
