Arlington Park (formerly known as Arlington International Racecourse) was a Thoroughbred race track in the Chicago suburb of Arlington Heights, Illinois, United States. Once called the Arlington Park Jockey Club, it was located adjacent to the Illinois Route 53 expressway and serviced by the Chicago and North Western Railway.

On February 15, 2023, the Chicago Bears of the National Football League (NFL) completed their purchase of the Arlington Park property. The team may build a stadium on the site for its home games.

In August 2025, the racetrack was fully demolished, and the Chicago Bears confirmed their plan for a new stadium at the site.
