Arthur Boyd Hancock III is an American owner of Thoroughbred racehorses, the owner of Stone Farm, a 2,000 acre horse breeding operation in Paris, Kentucky, and a composer of Bluegrass music.

Hancock is a member of one of the pre-eminent American horse racing families. His grandfather, Arthur B. Hancock, founded Claiborne Farm, his father, Arthur B. "Bull " Hancock, Jr., expanded the business to where it is considered the most important breeding farm in the U.S. during the 20th century and whose sales and influence also impacted European racing.

After graduating from Vanderbilt University, Hancock moved to the New York City area where he worked as an apprentice under future Hall of Fame trainer Edward A. Neloy. While Hancock's younger brother Seth would eventually take over the running of Claiborne Farm, Hancock built Stone Farm into a respected and successful breeding and racing operation which earned the family its first ever win in the Kentucky Derby. In partnership with one of his longtime clients, Manhattan real estate broker Leone J. Peters, he bred and raced Gato Del Sol who won the 1982 Derby.
