Vice Regent (April 29, 1967 – June 18, 1995)^[1] was a Canadian Hall of Fame Thoroughbred racehorse and Canada's leading sire for thirteen years. Owned and bred by E. P. Taylor, he was from Northern Dancer's second crop and out of the mare Victoria Regina, a daughter of the French multiple stakes winner Menetrier whom E. P. Taylor purchased as a sire from François Dupré and imported to Canada.

Vice Regent was a full brother to Viceregal who earned Canadian Horse of the Year honours as a two-year-old in 1968. As such, on his debut one year later in 1969, much was expected from Vice Regent. Conditioned by future Hall of Fame trainer Gordon J. McCann, as a result of injuries and an accident, Vice Regent raced only five times before being forced into retirement.

Standing at stud at his owner's Windfields Farm, his outstanding performance as a sire earned him a 1989 induction in the Canadian Horse Racing Hall of Fame. During his career, Vice Regent produced four hundred foals, of which sixty were stakes winners.
