Mount Gambier is the second most populated city in South Australia, with an estimated urban population of 33,233 as of 2021^[update]. The city is located on the slopes of Mount Gambier, a volcano in the south east of the state, about 450 kilometres (280 mi) south-east of the capital Adelaide and just 17 kilometres (11 mi) from the Victorian border. The traditional owners of the area are the Bungandidj (or Boandik) people. Mount Gambier is the most important settlement in the Limestone Coast region and the seat of government for both the City of Mount Gambier and the District Council of Grant.

The city is well known for its geographical features, particularly its volcanic and limestone features, most notably Blue Lake / Warwar, and its parks, gardens, caves and sinkholes.
