Baby LeRoy (12 May 1932 – 28 July 2001) was a child actor who appeared in films in the 1930s.

Born Ronald Le Roy Overacker in Los Angeles, California, Baby LeRoy's career began when he was less than a year old, co-starring with Maurice Chevalier in A Bedtime Story, and ended with a cameo role as himself in Cinema Circus (1937). He is best known for his appearances in a number of W. C. Fields films, including Tillie and Gus (1933) and It's a Gift (1934).

A starring role in the 1940 film The Biscuit Eater was to have been his comeback, but an accident during filming forced the director to choose between recasting or holding up production until he recovered. The director chose to recast, and the film became one of Billy Lee's best-remembered roles. In 1957, as an adult, he appeared as a guest challenger on the TV panel show To Tell The Truth.
