Churchill Downs has spent generations turning Kentucky Derby history into a wall of names, and the tradition still stretches across 151 winners on the grandstand paneling. Aristides was the first, Sovereignty was the latest, and a new ranking of 20 Derby horse names is now putting fresh attention on the way owners and trainers choose them.
Yahoo Sports ranked the 20 names, with Commandment at No. 1, The Puma at No. 2, Potente at No. 3, Renegade at No. 4 and Great White at No. 5. Litmus Test was No. 6, Emerging Market No. 7, Pavlovian No. 8, Further Ado No. 9 and Chief Wallabee No. 10. The list is a reminder that Derby horse names can sound like scripture, finance, a joke or a tribute, but they still have to fit the rules. The Jockey Club says names can be no longer than 18 characters, including spaces and punctuation, and they cannot be vulgar. Some can be reused after a period of time, but others are off-limits, including any horse in the Hall of Fame or former Triple Crown race winners.
The names that endure usually carry a story. Alysheba, the 1987 Kentucky Derby winner, was sired by Alydar out of a mare named Bel Sheba. I’ll Have Another, the 2012 winner, was named after the owner’s favorite expression when his wife baked cookies. Giacomo, the 2005 champion, was named by Jerry Moss after the son of Sting. Those choices show why Derby horse names often feel personal even when they are public, and why a good one can be part pedigree, part memory and part marketing.
The ranking also exposes how much owners use naming as a kind of private code. Seth Klarman has leaned on business or political phrases for his horses, with notable stakes winners including Domestic Spending, Early Voting and Program Trading. J. Paul Reddam and trainer Doug O’Neill campaigned Pavel from 2017 to 2019, and that connection helped inspire Pavlovian’s name. The Puma came from trainer Gustavo Delgado’s resemblance to Venezuelan singer Jose Luis Rodriguez, whose nickname in their home country is El Puma, while Potente is simply the Italian word for powerful. Litmus Test traces to a mare named Study Hard, and Chief Wallabee nods to the Wallabee shoe brand.
That mix of family history, personality and constraint is what gives Derby horse names their staying power. The scoreboard at Churchill Downs may celebrate the winners, but the names themselves are the part fans keep re-reading.
