1933 Major League Baseball season

The 1933 major league baseball season began on April 12, 1933. The regular season ended on October 1, with the New York Giants and Washington Senators as the regular season champions of the National League and American League, respectively. The postseason began with Game 1 of the 30th World Series on October 3 and ended with Game 5 on October 7. The Giants defeated the Senators, four games to one.

The first Major League Baseball All-Star Game was played on July 6, hosted by the Chicago White Sox at Comiskey Park in Chicago, Illinois, with the American League winning, 4–2.

The season featured eight players hitting for the cycle, tied for the most of any single major league season. It was also the last season before the Senators and Philadelphia Athletics became perennial American League cellar-dwellers. The Senators would have only four more winning seasons in Washington, D.C., and would not return to the World Series until 1965 as the Minnesota Twins, while the Athletics would have only four winning seasons until moving to Oakland in 1968, winning only 40.2 percent of their games over 34 seasons.

The 1933 schedule consisted of 154 games for all teams in the American League and National League, each of which had eight teams.
