The Peacock Sound is an icy strait of 215 km long and 60 km wide, which the Thurston Island from the Eights Coast in West Antarctic Ellsworth Land separates. It is not navigable because the western section is occupied by the Abbot Ice Shelf .

The sound was discovered in February 1940 during overflights during the United States Antarctic Service Expedition (1939-1941) and the position was determined using aerial photographs from Operation Highjump (1946-1947) in December 1946. The extent of the sound along the entire south coast of Thurston Island was broken down during the United States Navy expedition into the Bellingshausen Sea in February 1960. The sound is named after the USS Peacock , which under Captain William L. Hudson (1794-1862) together with the USS Flying Fish as part of the United States Exploring Expedition (1838-1842) in March 1839 for a few days on the pack ice border north of the Sailed along Thurston Island.
