Longhurst Plateau (79°23′S 156°20′E / 79.383°S 156.333°E / -79.383; 156.333) is a narrow, snow-covered extension of the Antarctic polar plateau located just west of Mount Longhurst. Rising to 2,200 metres (7,200 ft), it is about 20 nautical miles (37 km) long and 10 nautical miles (19 km) wide, and is bounded on the south by the upper part of Darwin Glacier and on the east by McCleary Glacier. The plateau was traversed by the Darwin Glacier Party of the Commonwealth Trans-Antarctic Expedition in 1957–58, who named it for nearby Mount Longhurst.
