The 1898 Major League baseball season began on April 15, 1898. The regular season ended on October 15, with the Boston Beaneaters as the pennant winner of the National League. Due to lack of enthusiasm from both players and fans, the Temple Cup which had taken place in the four previous seasons was not held, nor was there any other form of a postseason.
The Chicago Colts renamed as the Chicago Orphans.
