Mount Pinnacle, also known as Le Pinacle, is a mountain in Frelighsburg, Quebec, that rises to 712 metres and covers about 22 square kilometres. It is considered one of the few remaining unspoiled mountains in southwestern Quebec, notable for its relatively intact landscape. The mountain was originally inhabited by the Abenaki, giving it a history that reaches back long before modern settlement in the region. Its significance lies both in that deep human past and in its enduring place within the natural setting of southwestern Quebec.
