The McLaren M20 was a sports prototype developed by McLaren for the 1972 season of the Canadian-American Challenge Cup. It served as a replacement for the team's M8Fs, but it later became the final Can-Am design created by McLaren before the team left the series after failing to secure the 1972 championship title. M20s continued to be entered by private teams until the Can-Am championship was canceled at the conclusion of the 1974 season. McLaren driver Denny Hulme won two races during the 1972 season while Scooter Patrick won a single event in 1974 with a privately entered M20.
