Emil John "Dutch" Leonard (March 25, 1909 April 17, 1983) was an American professional baseball player. He played in in Major League Baseball as a right-handed knuckleball pitcher for the Brooklyn Dodgers (1933 36), Washington Senators (1938 46), Philadelphia Phillies (1947 48), and Chicago Cubs (1949 53).

Leonard's nickname 'Dutch' was also taken in his honor by crime novelist Elmore Leonard, and was tattooed as such during his time in the SeaBees.
