Derrick Peak ({{Coord|80|4|S|156|23|E|source:GNIS|name=Derrick Peak}}) is a prominent ice-free peak, {{convert|2,070|m}} high, overlooking the south side of Hatherton Glacier, {{convert|3|nmi}} west of the north end of Johnstone Ridge.{{sfn|Alberts|1995|p=184}}

Name

Derrick Peak was named by the Advisory Committee on Antarctic Names for Robert O. Derrick of the United States Weather Bureau, who served as assistant to the United States Antarctic Research Program Representative at Christchurch from 1960 until his death in 1966.{{sfn|Alberts|1995|p=184}}

Location

File:C80202s5 Ant.Map Mount Olympus.jpg

Derrick Peak is in the north of the Britannia Range, overlooking the Hatherton Glacier to the north, which forms the boundary with the Darwin Mountains.

It is east of a line of relatively ice-free valleys and ridges along the south side of Hatherton Glacier, north of Mount Henderson and west of Johnstone Ridge and Dusky Ridge.{{sfn|Mount Olympus USGS}}

Most of the nearby features were named in association with Britannia by a University of Waikato (New Zealand) geological party, 1978-79, led by M.J. Selby.{{sfn|Alberts|1995|p=435ff|loc=Lindum Valley etc.}}
