John Cannon (21 June 1933 – 18 October 1999) was a sports car racer, who competed under the banner of Canada, though he was born in London, U.K.

Cannon duplicated that accomplishment in 1968 propelled by a famous win over the dominant McLaren team in a very wet race at Laguna Seca.

Cannon ran in the Continental Series (Formula 5000) in 1969 winning races at Riverside, Sears Point and Mosport in the Malcolm Starr Eagle prepared by Tom Jobe and Bob Skinner and finishing fourth in the standings.

Cannon also made 15 starts in the USAC Championship Car series while driving on a part-time basis from 1968 to 1974.

Although Cannon held the Ferrari dealership (actually, he worked for Hollywood Sports Cars-he did not own it) for LA, finance and engine costs limited his form in highly competitive final years of US F5000, however he proved competitive when he ran a few rounds in the UK Shellsport F5000/F1/Libre series in 1976.
