Duclos-Guyot Bluff (Bulgarian: връх Дюкло Гийо, ‘Vrah Duclos-Guyot’ \'vrah dyu-'klo gi-'yo\) is the ice-covered peak rising to 1800 m at the south extremity of Urda Ridge on Clarence Island in the South Shetland Islands, Antarctica. It has precipitous and partly ice-free south slopes, and surmounts Skaplizo Glacier to the west and Dobrodan Glacier to the northeast.
The peak is named after the French mariner Nicolas Pierre Duclos-Guyot (1722-1794), second in command under Louis Antoine de Bougainville in the first French circumnavigation of the world, who sailed in Antarctic waters on board the Spanish ship León in 1756.
Duclos-Guyot Bluff is located at -61.2994°N -54.1244°W, which is 2.9 km northwest of Cape Bowles, 5.6 km east of Craggy Point and 2.4 km south of Mount Irving. British mapping in 1972 and 2009.
