Mount Haddington is a massive 1,630 m (5,350 ft) high shield volcano comprising much of James Ross Island in Graham Land, Antarctica.

It is 60 km (37 mi) wide and has had numerous subglacial eruptions throughout its history, forming many tuyas.

Haddington formed along the Larsen Rift dominantly during the Miocene and Pliocene epochs but more recent eruptions have produced tuff cones on its slopes.

Effusive eruptions have created large deltas composed of hyaloclastite breccia and lava flows.
