The 1909 St. Louis Browns season was a season in American baseball. It involved the Browns finishing 7th place in the American League with a record of 61 wins and 89 losses.

James Robert "Loafer" McAleer was an American center fielder, manager, and stockholder in Major League Baseball who assisted in establishing the American League. He spent most of his 13-season playing career with the Cleveland Spiders, and went on to manage the Cleveland Blues, St. Louis Browns, and Washington Senators. Shortly before his retirement, he became a major shareholder in the Boston Red Sox. His career ended abruptly. During his brief tenure as co-owner of the Red Sox, McAleer quarreled with longtime friend and colleague Ban Johnson, president of the American League. In the wake of this disagreement, he sold off his shares in the Red Sox and broke off his relationship with Major League Baseball.
