John Cairns Hubbard (27 June 1902 – 29 August 1997) was an English international rugby union player.
Born in Woolwich, London, Hubbard was the son of England three-quarter George Hubbard. He worked as a stock broker and spent most of his life in the Surrey town of Esher, where he moved in 1934.[1]
Hubbard gained his solitary England cap deputising injured fullback John Askew for a Calcutta Cup match against Scotland at Twickenham in 1930.[2] The match finished in a 0–0 draw and Hubbard's assured performance at fullback was credited with playing a large part in keeping the Scots score-less.[3] He won his England call up via Harlequins and also played club rugby with Blackheath, while for county fixtures he represented Kent.[4]
