Tiago (foaled March 8, 2004, died November 2015) was an American Thoroughbred racehorse who won the 2007 Santa Anita Derby and Awesome Again Stakes.

His dam was the stakes winning mare Set Them Free, by Stop The Music, making him a half-brother to 2005 Kentucky Derby winner Giacomo.

On January 23, Tiago finished second in another Maiden Special Weight race but was bumped to first place after the leader was disqualified for interference down the stretch.

On May 5, Tiago made his first appearance outside of Southern California racing circuit, placing seventh in the 133rd running of the Kentucky Derby, which was won by Street Sense at Churchill Downs.

Tiago was to make his first start against older horses in the August 19 Pacific Classic Stakes at Del Mar Racetrack but was scratched the morning of the race due to trainer John Shirreffs's apprehension about the Polytrack surface.

On September 29, he won the Grade 1 Goodwood Breeders' Cup Handicap at Santa Anita Park by a nose over Awesome Gem.

At the start of the Classic, he broke slowly and took up the rear behind Awesome Gem, Street Sense, and Curlin, Tiago finished fifth on the sloppy track.

Tiago remained mid pack along the backstretch but could not overtake the leaders when he tried to close down the stretch and finished third, two lengths behind the winner.
