Sydney Alfred Coventry (13 June 1899 – 10 November 1976) was an Australian rules football player, coach and administrator.

In 1996, Coventry was inducted into the first batch of players and officials in the Australian Football Hall of Fame.

In 2016, Coventry was named by Sam Walker of The Wall Street Journal as one of the 16 best captains in sport history.

He moved to Queenstown in Tasmania after World War II to work as a miner.

The footballers in the region are noted as some of the hardiest in Australia given the weather and playing conditions, which include the famous gravel oval at Queenstown.

Coventry initially agreed to sign with the Saints, but his brother Gordon—who had just played his first year with Collingwood—to join the Magpies instead.
