Thomas David Gorman (March 16, 1919 – August 11, 1986) was an American pitcher and umpire in Major League Baseball who pitched five innings in four games with the New York Giants in 1939, and went on to serve as a National League umpire from 1951 to 1976, then as a league supervisor. His son Brian has been a major league umpire since 1991 and wears the same uniform number 9 the elder Gorman wore after the NL began adding numbers to umpire uniforms in 1970.
