Dr. Joseph Beverly MacInnis, CM (born in Barrie, Ontario, Canada on 2 March 1937) is a Canadian physician, author, poet, underwater diver and aquanaut. In 1974, MacInnis was the first scientist to dive beneath the North Pole. In 1976 he became a member of the Order of Canada.

MacInnis is of Isle of Mull Scottish descent. He was born in Barrie, Ontario, but grew up in Toronto, where his family moved after his father, a Royal Canadian Air Force instructor, died in a plane crash when MacInnis was a few months old. MacInnis was raised by his mother, who remarried when he was 12. He attended high school at Upper Canada College.

MacInnis first learned to scuba dive in 1954 in the waters off Florida. He attended the University of Toronto, where he was the captain of the swim team in the mid-1950s. MacInnis held the Canadian record for the breaststroke and tried unsuccessfully to make the Canadian Olympic team in 1956. MacInnis received his MD from the University of Toronto in 1962. He spent his internship at the Toronto General Hospital, where an experience with a tunnel construction worker suffering from decompression sickness helped to point MacInnis toward his post-graduate studies in diving medicine. MacInnis arranged for the worker, John McGean, to be transported to a pressure chamber in Buffalo, New York, where he was successfully treated. MacInnis also interned at the Hospital for Sick Children in Toronto.
