The 2012 Tim Hortons Brier, the Canadian men's national curling championship, was held from March 3 to March 11 at the Credit Union Centre in Saskatoon, Saskatchewan. This Brier marked the sixth time that Saskatoon hosted the Brier; the last time that the Brier was hosted in Saskatoon was in 2004. The winner of the Brier, Glenn Howard, represented Canada at the 2012 Capital One World Men's Curling Championship in Basel, Switzerland.

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.
