Elections to the Baseball Hall of Fame for 1973 followed the system in place since 1971, plus the special election of Roberto Clemente, who had died in a plane crash on New Year's Eve. The Baseball Writers' Association of America (BBWAA) voted by mail to select from recent major league players and elected Warren Spahn. The Veterans Committee met in closed sessions to consider executives, managers, umpires, and earlier major league players. It selected three people: Billy Evans, George Kelly, and Mickey Welch. The Negro Leagues Committee also met in person and selected Monte Irvin. A formal induction ceremony was held in Cooperstown, New York, on August 6, 1973, with Commissioner of Baseball Bowie Kuhn presiding.

Monford Merrill "Monte" Irvin was an American left fielder and right fielder in the Negro leagues and Major League Baseball (MLB) who played with the Newark Eagles, New York Giants (1949–1955) and Chicago Cubs (1956). He grew up in New Jersey and was a standout football player at Lincoln University. Irvin left Lincoln to spend several seasons in Negro league baseball. His career was interrupted by military service from 1943 to 1945.
