Lieutenant-Commander John Hamilton Stubbs, DSO DSC (June 5, 1912 – 1944) was a Royal Canadian Navy officer.
In 1935, he was appointed navigation officer in the Canadian destroyer HMCS Skeena, and was promoted to lieutenant the following year.
For the next two years, Stubbs was mainly engaged in convoy escort duties in Assiniboine, though in August 1941 he escorted the battleship HMS Prince of Wales to Placentia Bay where British prime minister Winston Churchill met US President Franklin Roosevelt for the first time.
After attacking the submarine with machine gun fire, Stubbs rammed it twice and finally sank it with depth charges.
In 1944, whilst in command of the destroyer HMCS Athabaskan, Stubbs took part in the Action of 26 April 1944, which resulted in the destruction of the German torpedo boat T29.
