Jack Mogridge (1903-1978) was an Australian rugbly league player from the 1920s and later an administrator. Known as a tough forward, Jack Mogridge came to St. George Dragons from Warwick, Queensland after being spotted by club stalwart Arthur Justice in Armidale in 1927. He spent two seasons at the Dragons, but suffered a serious broken leg injury in 1929, which finished his career prematurely. Mogridge stayed with the St. George Dragons in an administrative capacity, later becoming club treasurer, a selector and the club delegate to the NSWRFL. In later years, Jack Mogridge was the publican of the Kogarah Hotel, in Kogarah, New South Wales.
