Edwin Lee Mathews was an American professional baseball third baseman. He played in Major League Baseball (MLB) for 17 seasons for the Boston / Milwaukee / Atlanta Braves (1952–1966); Houston Astros (1967) and Detroit Tigers (1967–68). Inducted into the National Baseball Hall of Fame in 1978, he is the only player to have represented the Braves in the three cities they have called home. He played 1,944 games for the Braves during their 13-season tenure in Milwaukee—the prime of Mathews' career.

A third baseman, abbreviated 3B, is the player in baseball or softball whose responsibility is to defend the area nearest to third base — the third of four bases a baserunner must touch in succession to score a run. In the scoring system used to record defensive plays, the third baseman is assigned the number 5.
