The Brugmann Mountains (), rising to 850 metres (2,800 ft), are steep and rugged on the east slopes but are icecapped and descend gently toward the west, extending in a northeast–southwest arc along the east side of Liège Island, in the Palmer Archipelago. They were discovered by the Belgian Antarctic Expedition under Gerlache, 1897–99, and named by him for Georges Brugmann, a patron of the expedition.
