West Side Park was the name used for two different ballparks that formerly stood in Chicago, Illinois. They were both home fields of the team now known as the Chicago Cubs of the National League. Both ballparks hosted baseball championships. The latter of the two parks, where the franchise played for nearly a quarter century, was the home of the first two world champion Cubs teams ( and ), the team that posted the best winning percentage in Major League Baseball history and won the most games in National League history (), the only cross-town World Series in Chicago (1906), and the immortalized Tinker to Evers to Chance double-play combo. Both ballparks were primarily constructed of wood. The first West Side Park (1885–1891) The initial stadium was the club's home beginning in , succeeding Lakefront Park.

The club spent the first five-plus weeks of the 1885 season on the road, and the park was finally opened on June 6 with a victory over the St. Louis Maroons, late of the Union Association. Despite being "wanderers" early in the season, the powerful Chicago club, under player-manager Cap Anson, came home with an 18–6 record.
