Jack Donohue is a former NASCAR driver from Nobleton, Ontario, Canada. He competed in five Nextel Cup events in his career.
He appeared in 1974, running at Nashville and Dover. Starting 27th in his series debut at Nashville, Donohue completed half the laps before engine failure left him 19th, still a career-best finish. Another broken engine the next week at Dover left him 29th.
In 1976, Donohue raced his final three events. He matched his career-best 19th place effort at Dover, his first career race he was running at the finish. He was also running at the finish at Rockingham (21st), but didn't complete a lap in his final career race at Atlanta (36th).
