Brown Peak is a stratovolcano and the highest point of the Balleny Islands. It is situated on the northern part of Sturge Island. Recent research suggests this may be as high as 2170m.
John Balleny discovered Brown Peak in February 1839, and named it for William Brown, a Glasgow merchant who provided financial support to the Enderby Brothers' expedition. In 1841, Captain James Clark Ross, who sighted the islands on his own expedition to Antarctica, gave it the name Russell Peak.
Satellite imagery suggests that an eruption may have occurred on or about 12 June 2001.
