The 1909 major league baseball season began on April 12, 1909. The regular season ended on October 7, with the Pittsburgh Pirates and Detroit Tigers as regular season champions of the National League and American League, respectively. The postseason began with Game 1 of the sixth modern World Series on October 8 and ended with Game 7 on October 16. The Pirates defeated the Tigers, four games to three.

In the National League, the Chicago Cubs had a record of 104–49 but finished 6+1⁄2 games behind the Pirates, setting a record for the most wins in an MLB regular season without reaching the postseason, which has only been equaled once, by the 1942 Brooklyn Dodgers, who had a record of 104–50.[1]
