Berrister Gap (, ) is the ice-covered 3.7 km long saddle of elevation 191 m on western Livingston Island in the South Shetland Islands, Antarctica, linking Casanovas Peak on the northeast to Rotch Dome on the southwest. It is part of the glacial divide between Verila Glacier on the southeast and Etar Snowfield on the northwest. The area was known to early 19th century sealers. The gap was visited by a field party from the British base camp Station P during the summer season 1957/58.
The feature is named after Andrew Berrister, a fictional scientist from Simon BeaufortâÂÂs novel The Killing Ship, who crossed the gap while running for help from Hannah Point to Barclay Bay.
