The Cordiner Peaks (-82.8°N -83°W) are a group of peaks extending over an area of standing southwest of Dufek Massif in the northern part of the Pensacola Mountains, Antarctica.
The Cordiner Peaks were discovered and photographed on January 13, 1956, in the course of a transcontinental nonstop plane flight by personnel of United States Navy Operation Deep Freeze I from McMurdo Sound to the Weddell Sea and return. They were named by the United States Advisory Committee on Antarctic Names for Captain Douglas L. Cordiner, U.S. Navy, an observer on the P2V-2N Neptune aircraft making this flight. The entire Pensacola Mountains were mapped by the United States Geological Survey (USGS) in 1967 and 1968 from ground surveys and from United States Navy tricamera aerial photographs taken in 1964.
The Cordiner Peaks are to the east of the mouth of the Foundation Ice Stream on the Ronne Ice Shelf.The Jaburg Glacier flows westward past their north side, to the south of the Dufek Massif.They are north of the Spanley Rocks at the north end of the Neptune Range.Features, from north to south, include Rosser Ridge, Sumrall Peak and Jackson Peak.
