John Mowbray (1940-2009) was an Australian former professional rugby league footballer who played in the 1950s and 1960s.
Mowbray was born in Springwood and played his junior rugby league with the Guildford Owls in the Parramatta district.
Mowbray then went and trialed with Western Suburbs and was successful in obtaining a contract after starring in a pre-season match against Parramatta at Cumberland Oval.
The grand final is widely remembered for the muddy conditions during the match and the photograph of Norm Provan and Arthur Summons which was taken at full time.
This would be the last grand final that Western Suburbs would play in as a stand-alone entity until they exited the competition in 1999.
