Joseph Hilarian Hatten (November 7, 1916 – December 16, 1988) was a Major League Baseball pitcher.
Hatten started in pro ball with Crookston in the old Northern League in 1937. Acquired by the Montreal Royals from the Minneapolis Millers of the American Association in the 1941–42 off-season, Hatten pitched for the Royals briefly in 1942 before entering the U.S. Navy. Upon his discharge four years later, he first saw service with the Brooklyn Dodgers. Possessing a "rubber arm", Hatten worked as both a starting pitcher and a reliever, even appearing in both ends of a double-header.
Hatten's first year in the big leagues in 1946 saw him post a 14–11 won-lost record with a 2.84 ERA, eighth-best in the National League. He followed that season with a career-high 17 wins, eight losses and a 3.63 ERA. Hatten often had trouble controlling his pitches, as he allowed the second-most bases on balls in each of his first two seasons with the Dodgers, walking 110 batters in 1946 and 105 in 1947. He also led the National League in hit batsmen with seven in 1946. In 1948, Hatten threw 51 pitches in a five-inning complete game shutout against Cincinnati, the fewest pitches for a complete game in major league history.
The left-handed Hatten pitched for the Dodgers from 1946 through 1951, finishing his career with the Chicago Cubs in 1952. His career record was 65–49 with a 3.87 ERA.
