Mercury Bluff is a perpendicular bluff on Gerlovo Beach in the northwest of Ioannes Paulus II Peninsula, Livingston Island in the South Shetland Islands, Antarctica. The area was visited by early 19th century sealers.
The feature is named after the British sealing ship Mercury under Captain Robert Wetherell that operated out of the nearby Shirreff Cove in 1820–21.
The point is located at -62.4899°N -60.8243°W which is 3.9 km south-southwest of Cape Shirreff, 2.28 km north of Kudoglu Point and 12 km north-northeast of Rowe Point and 20.85 km east-northeast of Essex Point (British mapping in 1821 and 1968, Chilean in 1971, Argentine in 1980, Spanish in 1991, and Bulgarian in 2005 and 2009).
