Coulman Island is an ice-covered island, composed of several connected shield volcanos in the Ross Sea off Antarctica. It is 33.3 kilometres (18 nmi) long and 14.8 kilometres (8 nmi) and is located 17 kilometres (9 nmi) SE of Cape Jones, Victoria Land. The Coulman caldera, 4.8 kilometres (3 mi) wide and 701 metres (2,300 ft) deep, can be found on the south end of the island. Emperor penguins inhabit this island. Coulman Island lies within the boundaries of Ross Dependency, which is claimed by New Zealand; a claim unrecognised by most other states. It was discovered in 1841 by Sir James Clark Ross who named it for his father-in-law, Thomas Coulman. A notable landmark of this island is Cape Anne, the south-easternmost point of the island, so named by Sir James Clark Ross for his wife.
