Boulton Peak (64°6′S 60°42′W / 64.100°S 60.700°W / -64.100; -60.700) is a peak at the southeast side of Curtiss Bay, about 5 nautical miles (9 km) south of Cape Andreas in Graham Land, Antarctica. It surmounts Pirin Glacier to the north and Gregory Glacier to the south.

It was mapped from air photos taken by Hunting Aerosurveys Ltd (1955–57). It was named by the UK Antarctic Place-Names Committee for Matthew Piers Watt Boulton, the English inventor of ailerons for lateral control of aircraft, in 1868.^[1]
