Laclavère Plateau (63°27′S 57°47′W / 63.450°S 57.783°W / -63.450; -57.783 (Laclavère Plateau)) is a plateau, 10 nautical miles (19 km; 12 mi) long and from 1 to 3 nautical miles (1.9 to 5.6 km; 1.2 to 3.5 mi) wide, rising to 1,035 metres (3,396 ft) between Misty Pass and Theodolite Hill, Trinity Peninsula, Antarctica. The plateau rises south of Schmidt Peninsula and the Chilean scientific station, Base General Bernardo O'Higgins Riquelme.^[1]

Laclavère Plateau is in Graham Land towards the north of the Trinity Peninsula, which forms the tip of the Antarctic Peninsula. It is southeast of the Huon Bay, south of the Duroch Islands and Schmidt Peninsula, west of the Mott Snowfield and Duse Bay and north of Broad Valley. Named features include Misty Pass in the west and Theodolite Hill in the east.^[2][3]

'Laclavère Plateau was named by the UK Antarctic Place-Names Committee (UK-APC; 1963) after French cartographer Georges R. Laclavère, President of the Scientific Committee on Antarctic Research (SCAR), 1958–63.^[1]
