The Pegasus Stakes is an American Grade III Thoroughbred horse race run annually in June at Monmouth Park Racetrack in Oceanport, New Jersey. An event for three-year-olds of either gender, it is contested at a mile and an eighth (nine furlongs) on the dirt, and offers a purse of $250,000.

There was no race run in 2003 and the 2007 was held at Monmouth Park, the Meadowlands' sister track, on the Breeders' Cup undercard. It was again run at Monmouth Park in 2010. In 1995 and 1996 the race was run at a distance of 11/16 miles. The 1996 edition was raced on the turf course.

Sally Bailie became the first woman trainer in the history of American Thoroughbred racing to win a $200,000 race when she captured the 1982 edition of the Pegasus Handicap with Fast Gold.
