Mont Saint-Bruno (French pronunciation: [mɔ̃ sɛ̃ bʁyno]) is part of the Monteregian Hills in southern Quebec, Canada.

Its summit stands 218 m (715 ft) high and lies 23 km (14 mi) east of downtown Montreal.

Forests of beech, maple, oak, hickory, ironwood, hemlock and pine cover those slopes which have not been cleared for agriculture or skiing.

Mont Saint-Bruno might be the deep extension of a vastly eroded ancient volcanic complex, which was probably active about 125 million years ago.

As a result, Mont Saint-Bruno forms part of the Great Meteor hotspot track.
