The 1898 Chicago Orphans season was the 27th season of the Chicago Orphans franchise, the 23rd in the National League and the sixth at West Side Park. The Orphans, formerly known as the Colts, finished in fourth place in the National League with a record of 85–65, 17.5 games behind the Boston Beaneaters.
1898 was the first season since 1876 that the team was without manager and first baseman Cap Anson, who had been fired during the offseason. Cap, who was also often called "Pop", was replaced as manager by Tom Burns, who had played for the team from 1880 until 1891, and had managed the Springfield Ponies in 1897. The media, picking up on Anson's absence, began referring to the team as the "Orphans", as they had lost their "Pop".
