The Ontario Tankard is the Southern Ontario provincial championship for men's curling. The winner represents Team Ontario at the Montana's Brier. The tournament is overseen by CurlON (formerly the Ontario Curling Association).
Northern Ontario has its own provincial championship, known as the Northern Ontario Men's Provincial Curling Championship.
This championship is not to be confused with the Silver Tankard, historically also known as the Ontario Tankard (and until 1937 a Brier qualifier).
