The Churchill Downs Cup (Japanese: チャーチルダウンズカップ) is a Grade 3 horse race organized annually by the Japan Racing Association (JRA) for three-year-old Thoroughbreds. It is run in April over a distance of 1600 metres at Hanshin Racecourse.

The race was first run in 1992 and has held Grade 3 status ever since. It serves as a trial race for the NHK Mile Cup. Past winners of the race have included Eishin Preston, Tanino Gimlet, Just A Way and Mikki Isle. Formerly named Arlington Cup, it was renamed to Churchill Downs Cup in 2025.
