The 1931 Philadelphia Athletics season involved the A's finishing first in the American League with a record of 107 wins and 45 losses. It was the team's third consecutive pennant-winning season and its third consecutive season with over 100 wins. However the A's lost the 1931 World Series to the St. Louis Cardinals in seven games. The series loss prevented the Athletics from becoming the first major league baseball team to win three consecutive World Series; the New York Yankees would accomplish the feat seven years later. The Athletics, ironically, would go on to earn their own threepeat in 1974, some forty-three years after the failed 1931 attempt.
1931 was also the A's final World Series appearance in Philadelphia. Their next AL pennant would be in 1972, after they had moved to Oakland.
