Charlie Fox (27 July 1898 – January 1985) was an Australian rugby union player, a state and national representative second-rower who made 36 appearances for the Wallabies, playing in 17 Test matches and captained the national side on seven occasions (one Test match) in 1925.
Charles Fox was twenty-one years of age and playing for the Glebe-Balmain Club in Sydney when he was selected in 1919 to play in an invitation Australian XV against an AIF side, a match which marked a re-kindling of interest in rugby union in Sydney following WWI.
The 3rd test of 1925 played on 23 June at the Sydney Showground was Fox's sole appearance as the national captain.
He played in ten of the first thirteen games of the trip until he suffered a severe leg injury in the tour match loss to Oxford University RFC.
He was captain in that Oxford game and with no substitutes allowed, the Waratahs played the second half with 14 men and lost to the students 0–3.
