The 2011 Tim Hortons Brier, the Canadian men's national curling championship, was held March 5 until March 13, 2011 at the John Labatt Centre in London, Ontario. This event marked the 30th time that the province of Ontario has hosted the Brier since it began in 1927 in Toronto, Ontario and the first time a Bronze Medal Game was added to the playoffs.

The Brier, known since 2023 as the Montana's Brier for sponsorship reasons, is the annual Canadian men's curling championship, sanctioned by Curling Canada. The Brier has been held since 1927, traditionally during the month of March.
