The Derwent Hunter Guyot is an extinct volcanic seamount of the Tasmantid Seamount Chain.
It is a basaltic volcano that erupted between 12,400,000 and 15,400,000 years ago, with survey data that indicates it rises about 4,000 m (13,000 ft) above the local sea floor to a minimum depth of 323 m (1,060 ft). The sediments deposited on top of the alkali olivine basalt originate from the early Middle Miocene. The Derwent Hunter Guyot appears to be double peaked. It was discovered in 1958 and described as a seamount in 1961.
The waters above it are incorporated in the Central Eastern Marine Park, an Australian marine park.
