John Theodore Salveson (January 5, 1914 – December 28, 1974) was an American Major League Baseball pitcher who played for five seasons.

He played for the New York Giants from 1933 to 1934, the Pittsburgh Pirates and the Chicago White Sox in 1935, and the Cleveland Indians in 1943 and 1945.

In 1942, he won 24 games with the Oakland Oaks, enough to earn him a shot at the majors for the first time in eight years.

Salveson also appeared in the movie Pride of the Yankees as a pitcher who hit Lou Gehrig (played by Gary Cooper) in the head with a pitch.
