The Arlington Million is a Grade 1 flat horse race in the United States for thoroughbred horses aged three years and upward on turf. It was originally raced at Arlington Park in Arlington Heights, Illinois over a distance of 1+1⁄4 miles.
The Arlington Million is the first thoroughbred race to offer a purse of US$1,000,000. It is part of the Breeders' Cup Challenge series, and the winner automatically qualifies for the Breeders' Cup Turf.
Churchill Downs, whose parent company owned the land of the defunct Arlington Park racetrack, hosted the Arlington Million in 2022. The 2023 race was run at Churchill-owned Colonial Downs in Virginia.
