The Kentucky Derby is a horse race that is held annually in Louisville, Kentucky, United States, on the first Saturday in May, capping the two-week-long Kentucky Derby Festival. The race is a Grade I stakes race for three-year-old Thoroughbreds at a distance of one and a quarter miles (2.0 km) at Churchill Downs. Colts and geldings carry 126 pounds (57 kilograms) and fillies 121 pounds (55 kilograms).

The race is often called "The Run for the Roses" because of the blanket of roses draped over the winner. It is also known in the United States as "The Most Exciting Two Minutes In Sports" or "The Fastest Two Minutes in Sports" in reference to its approximate duration. It is the first leg of the American Triple Crown and is followed by the Preakness Stakes, then the Belmont Stakes.

The attendance at the Kentucky Derby ranks first in North America and usually surpasses the attendance of all other equestrian stakes races including the Preakness Stakes, Belmont Stakes, and the Breeders' Cup.
