Christopher Frank Stuart Irwin (born 27 June 1942 in Wandsworth, London) is a British former racing driver.

Irwin's career was ended prematurely by an accident he sustained when driving a Ford P68 sports prototype during practice for the 1968 1000km Nürburgring endurance race.

Irwin is still alive and reasonably well, but his whereabouts are largely unknown as he stays out of the public eye and away from motor racing events.

In a rare appearance at a race meeting, Irwin attended the Thruxton Circuit's 40th anniversary celebrations in April 2008.

A three-quarter page interview and a current photograph of him posing with old 1960s rivals and a Formula 2 car appeared in the June 2008 issue of Motor Sport magazine.
