Joe LeRoy Brown (September 1, 1918 – August 15, 2010) was an American front office executive in Major League Baseball.
Brown served as the general manager of the Pittsburgh Pirates from November 1, 1955, through the end of the 1976 season. Under his administration, the Pirates recovered from four consecutive last-place finishes in the National League to world championships in 1960 and 1971. Led by the great Baseball Hall of Fame players Roberto Clemente and Willie Stargell, the Bucs were perennial contenders in the National League (and, after 1969, the National League East Division).
Brown was a native of New York, but grew up in Southern California. The son of actor-comedian Joe E. Brown (Some Like It Hot), he inherited his father's passion for baseball. Brown first met Branch Rickey, his predecessor in Pittsburgh, when Brown was 16 years of age, in 1935. He entered minor league baseball after his graduation from UCLA in 1939 as a front-office official with the Lubbock Hubbers of the Class D West Texas–New Mexico League. He served in the United States Army Air Forces during World War II, then joined the Hollywood Stars of the Triple-A Pacific Coast League in 1946.
