Joseph John "Unser Choe" Hauser (January 21, 1899 in Milwaukee, Wisconsin – July 11, 1997 in Sheboygan, Wisconsin) was a professional baseball player who played 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.
