Mount Belinda is a stratovolcano located on Montagu Island, in the South Sandwich Islands of the Scotia Sea. A part of the British Overseas Territory, the South Georgia and the South Sandwich Islands, it is considered the only active volcano in the United Kingdom.

Belinda was inactive until late 2001, when it erupted. The eruption produced large quantities of basaltic lava, melting the thick cover of ice that had accumulated while the volcano lay dormant, and "producing a marvelous 'natural laboratory'; for studying lava-ice interactions relevant to the biology of extreme environments as well as to processes believed to be important on the planet Mars."

Mount Belinda has been in a persistent state of eruption since 2001. Far from slowing down, the activity throughout 2005 marks the highest levels yet. An increase in activity in the fall of 2005 has produced an active 3.5-kilometre (2.2-mile)-long lava flow, extending from the summit cone of Mount Belinda all the way down into the sea. The flow spreads northeast from the volcanic vent, and then becomes diverted due north by an arête.
