1946 Major League Baseball season

The 1946 Major League Baseball season was contested from April 16 to October 15, 1946. The St. Louis Cardinals and Boston Red Sox were the regular season champions of the National League and American League, respectively. The Cardinals defeated the Brooklyn Dodgers in a best-of-three series, for the National League title. It was Major League Baseball's first-ever regular season tie-breaker. The Cardinals then defeated the Red Sox in the World Series, four games to three.

Many notable ballplayers returned from their military service this season, following the end of World War II, such as Joe DiMaggio, Stan Musial, and Ted Williams.

This was the last MLB season to be played under the color barrier, as Jackie Robinson would make his debut with the Brooklyn Dodgers to start the following baseball season.
