Mount Jacquinot (63°22′S 57°53′W / 63.367°S 57.883°WCoordinates: 63°22′S 57°53′W / 63.367°S 57.883°W) is a pyramidal peak, 475 metres (1,560 ft) high, with exposed rock on its north side, lying 3 miles (5 km) south of Cape Legoupil and 1 mile (1.6 km) east of Huon Bay, on the north side of Trinity Peninsula, Antarctica. It was discovered by a French expedition, 1837–40, under Captain Jules Dumont d'Urville, who named it for Lieutenant Charles Jacquinot, the commander of the expedition corvette Zelée.
There was some controversy regarding claims of who found the continent first — Edward Bransfield or Nathaniel Palmer. In these debates, Mount Jacquinot figured prominently.
