Lemon Drop Kid (foaled 1996) is a Champion American Thoroughbred racehorse. He is among many stakes-winning Thoroughbreds to be descended from Triple Crown winner Seattle Slew. Seattle Slew is the sire of his dam, Charming Lassie. Kingmambo was his sire, himself a son of the very important Champion sire Mr. Prospector and out of the great mare, Miesque.

Lemon Drop Kid played the spoiler to Charismatic's 1999 U.S. Triple Crown run, winning the Belmont Stakes that year by catching the frontrunning Charismatic in the homestretch. Lemon Drop Kid followed up with a win in the important Grade I Travers Stakes. In 2000, he had an outstanding year, winning several major Grade I races and earning U.S. Champion Older Male Horse honors.

Lemon Drop Kid currently stands in stud at Lane's End Farm in Versailles, Kentucky where he commands US$20,000 for a single live cover breeding. His first crop of foals in 2005 produced three stakes winners. His second crop in 2006 produced three more stakes winners, including the filly Lemons Forever, the longshot winner of the 2006 Kentucky Oaks. In 2009, his daughter Santa Teresita (horse) won the Grade I Santa Maria Handicap.
