Denis of Cork (foaled February 16, 2005 in Florida) is an American Thoroughbred racehorse, graded stakes winner, and stallion.

He was purchased a second time in the Barretts March Two-Year Olds In Training auction in 2007 for $250,000 by Mr. William K. & Mrs. Suzanne Warren Jr.

Despite this, his earnings were enough to score him a spot in the 2008 Kentucky Derby, where he finished 3rd behind champion colt, Big Brown, and the ill-fated filly, Eight Belles.

However, when Denis of Cork returned from the Belmont Stakes, it was discovered that the colt had suffered from a pre-condylar fracture in one of his hind ankles.

Denis of Cork spent the 2009 winter at Fair Grounds Race Course after being returned to his trainer when he had fully recovered from a stifle injury suffered in January 2009.

[3] Standing alongside stallions Juba, Luftikus, and Windsor Castle, his best foals include stakes runners Romantic Cork, Celtic Moon, Return to Denis, and Bray's Secret.
