McAuslan Brewing is a Canadian brewery opened in January 1989, and its headquarters located in Montreal, Quebec, Canada.

McAuslan is still located on St-Ambroise street in the St-Henri borough and currently produces approximately 70,000 HL of beer annually.

In June 2008, Les Brasseurs RJ and La Brasserie McAuslan announced a business partnership specifically for sales, marketing and distribution of their respective brands both within Quebec and beyond.

During the summer months, Terrasse St-Ambroise is open behind the brewery on the Lachine Canal bike path near the Cote-St-Paul locks.
