John "Johnno" Stuntz (1884–1917) was an Australian pioneer rugby league footballer and soldier who served in World War I and died on the Western Front.

In Easts' first match – the opening game of club rugby league in Australia, he scored four tries.

This tally remains, equally with Jordan Atkins and Charlie Staines, the most tries scored on début in Australian premiership history.

In 2004 the Australian Rugby League granted Stuntz and his teammates retrospective representative status for the international games played against the Maori.

He embarked from Sydney on board HMAT A18 Wiltshire in August 1916 as a Private in the 14th reinforcement raised for the 17th Battalion of the 5th Brigade (New South Wales).
