Perfect Drift (April 29, 1999 – January 4, 2024) was an American thoroughbred racehorse who won or placed in 21 stakes races in his career.

Foaled in Kentucky, Perfect Drift was a bay gelding sired by the leading stallion Dynaformer, out of the Naskra mare Nice Gal.

He trained Perfect Drift throughout almost his entire career at his own 55-acre (220,000 m2) Trackside Stable in Louisville, Kentucky.

Perfect Drift won on both dirt and turf, at distances ranging from 6½ furlongs to 1 and a quarter miles.

This allowed Proud Citizen to take second, but Perfect Drift still took third, ahead of Medaglia d'Oro, Harlan's Holiday, Essence of Dubai, and Saarland.

On November 7, 2006, Murray Johnson announced that he believed a breathing problem hindered Perfect Drift's run in the Classic.

Perfect Drift has been ridden by a dozen or so jockeys, including Hall of Famers Eddie Delahoussaye, Pat Day and Gary Stevens, all now retired.

In July 2007, it was reported that Perfect Drift had a small fracture in his cannon bone, possibly career-threatening, and that he would be turned out for several months before being re-evaluated.

The injury was believed to have occurred on May 4 during the Alysheba Stakes on a sloppy track at Churchill Downs, when Perfect Drift placed fourth behind Wanderin Boy.

He underwent surgery to repair this injury (the insertion of a screw) in the fall of 2007 and was then placed in the care of trainer Richard Mandella.

This makes him the seventh richest gelding by lifetime earnings in North America, behind Wise Dan, John Henry, Game on Dude, Best Pal, Lava Man, and Well Armed.
