For the shoe, see: Sperry Top-Sider

Topsider (1974–1992) was an American Thoroughbred racehorse. He was a bay son of the great Northern Dancer and the very speedy racing mare Drumtop.

Topsider won eight races from eighteen career starts, including the Sport Page Handicap at Aqueduct Racetrack in New York City. In another of his wins he set a new track record of 1:14 2/5 for 6½ furlongs at Saratoga Race Course.
