John Thomas Sproule (5 December 1876 - 10 November 1940) was a Conservative member of the House of Commons of Canada. He was born in Lambton County, Ontario and became a farmer, a livestock dealer, and a businessman in the oil and cement industry.
Sproule served on the Oil Springs municipal council for 25 years and was the village's reeve for 11 years. He became a director of the Ontario Good Roads Association in 1924. Sproule was an unsuccessful candidate in the 1926 Ontario election.
