John Dennis 'Jiggy' Harris (4 November 1903 – 29 June 1993)[1] was an Australian rules footballer who played with Collingwood and Hawthorn in the VFL.
The son of Charles Ernest Harris (1873–1943),[2] and Florence Harris (1876–1954), née Harris,[3] John Dennis Harris was born at Mildura, Victoria on 4 November 1903.
His brother, Stanley William Harris (1909–1964), was a VFL footballer with Richmond and Footscray.
Recruited from Brighton, Harris started his career at Collingwood where he played as both a wingman and half forward flanker. He was a member of Collingwood premiership sides in 1927 and 1928. After being dropped for the 1929 Grand Final, thus missing out on a third successive premiership, Harris left Collingwood and joined Hawthorn as captain-coach. He spent two seasons with Hawthorn before joining VFA club Coburg where he played in a losing grand final in 1933.
