Mendoza Cove (Bulgarian: залив Мендоса, romanized: zaliv Mendoza, IPA: ['zaliv mɛn'dɔsɐ]) is the 1.65 km (1.03 mi) wide cove indenting for 680 m (2,230 ft) the south coast of Elephant Island in the South Shetland Islands, Antarctica east of Muckle Bluff. It was formed as a result of the retreat of the island's ice cap in the late 20th century. The area was visited by early 19th century sealers.

The feature is named after José de Mendoza y Ríos (1761–1816), a Spanish astronomer and mathematician who redesigned the reflecting circle; in association with other names in the area deriving from the early development or use of geodetic instruments and methods.

Mendoza Cove is centred at 61°09′15″S 54°50′35″W / 61.15417°S 54.84306°W / -61.15417; -54.84306, which is 7.7 km west of Walker Point. British mapping of the area in 1822,1972 and 2009.
