The Toronto Cup Stakes is a Canadian Thoroughbred horse race run annually on turf at Woodbine Racetrack in Toronto.

Inaugurated in 1890 as the Toronto Cup Handicap at the Old Woodbine Racetrack, it was raced on dirt and open to older horses until 1935.

There was no race in 1918 and 1919 and was suspended in 1935 then revived in 1953 restricted to three-year-olds and competed at a distance of 1+1⁄16 miles on dirt.

Since 1958 the race has been run on the turf with the exception of 1968 when it had to be switched to the main dirt track.

In 1987 the turf race was modified to its present 1+1⁄8 miles except for 1994 when it was held at the Fort Erie Racetrack and run at its old 1+1⁄16-mile distance.
