Lagrange Peak (64°28′S 62°26′W / 64.467°S 62.433°W / -64.467; -62.433) is a conspicuous peak, 450 metres (1,500 ft) high, standing 5.5 nautical miles (10 km) northeast of Strath Point on the southeast coast of Brabant Island, in the Palmer Archipelago, Antarctica. A point on the coast just south of this peak was first charted and the name Lagrange applied by the Belgian Antarctic Expedition under Gerlache, 1897–99. On one of the photos published by the expedition, the name is applied to the southern tip of the island. To avoid confusion, the generic term has been altered and the name applied to this peak.
