The Nassau Stakes is a Canadian Thoroughbred horse race held annually at Woodbine Racetrack in Toronto, Ontario. A Grade II event raced in early June, it is open to horses aged three and older and run over a distance of one mile on turf. Currently, the Nassau Stakes offers a purse of $300,000. Inaugurated in 1956, it was raced on dirt until 1968 when it was shifted permanently to the turf. Over the years, it has been run at various distances both at the Woodbine Racetrack and at Fort Erie Race Track.
