The Abbot Ice Shelf (72º45´S 096º00´W) is an ice shelf 400 km (250 mi) long and 64 km (40 mi) wide, bordering Eights Coast from Cape Waite to Phrogner Point . Thurston Island lies along the northern edge of the western half of this ice shelf; other sizable islands (Sherman, Carpenter , Dustin, Johnson , McNamara , Farwell and Dendtler ) lie partly or wholly within it.

The ice shelf was sighted by members of USAS in flights from the ship Bear, in February 1940, and its western portion was delineated from air photos taken by USN Operation Highjump, 1946-47. The full extent was mapped by USGS from USN air photos of 1966. Named by US-ACAN for R. Admiral J. Lloyd Abbot, Jr., Commanding Officer, U.S. Naval Support Force, Antarctica, February 1967 to June 1969.
