John Francis Thomas Ryan (3 December 1914 – 31 July 1976) was an Australian rules footballer who played with Footscray and North Melbourne in the Victorian Football League (VFL).
Ryan came to Footscray from Maryborough and topped their goal-kicking in 1935, his debut season, with 25 goals.[1] The following year he was selected to represent the VFL against the Victorian Football Association.[2] He was a regular fixture in the Footscray side, as a wingman, for another three seasons before being traded to North Melbourne, in exchange for Ted Ellis, in 1940.[3]
