Alphabet Soup (March 31, 1991 – January 28, 2022) was an American Thoroughbred racehorse best known for setting a track record for 1¼ miles at Woodbine Racetrack when he won the 1996 Breeders' Cup Classic, defeating both the great Cigar and Preakness Stakes winner Louis Quatorze.

He was bred by Southeast Associates, a group led by Roy S. Lerman, and purchased by Californian Georgia B. Ridder.

Mrs. Ridder raced the colt in California, where he began to come into his own at the age of four, winning the 1995 Native Diver and Del Mar Breeders' Cup Handicaps.

Alphabet Soup raced in 1997 at age six, his best effort coming in defense of the San Antonio Handicap when he finished second to Gentlemen.

He was euthanized due to chronic kidney disease, at Old Friends Thoroughbred Retirement in Georgetown, Kentucky, on January 28, 2022, at the age of 30.
