Joseph John Hauser (January 21, 1899 – July 11, 1997), nicknamed "Unser Choe", was an American professional baseball player who was a first baseman in the major leagues from 1922 to 1929, with the Philadelphia Athletics and Cleveland Indians. Hauser's major league career was undistinguished, but he made a name for himself in the minor leagues, where he became the first player ever to hit 60 or more home runs twice in a professional career: 63 in 1930, and 69 in 1933.
