Dunedin is the second-largest city in the South Island of New Zealand, and the principal city of the region of Otago. Dunedin is New Zealand's fifth largest city in population, the largest in size of council boundary area, and the hub of the fifth-largest urban area. For historical and cultural reasons and its location, Dunedin is considered one of the country's four main centres, although Hamilton has overtaken it in urban-area population.

The city stands on the hills and valleys surrounding the head of Otago Harbour. The harbour and hills are the remnants of an extinct volcano.

Dunedin is also notable now as centre for ecotourism. Uniquely, the world's only mainland Royal Albatross colony and several penguin and seal colonies lie within the city boundaries on Otago Peninsula.

The thriving student population has led to a vibrant youth culture, consisting of the before mentioned music scene, and more recently a burgeoning boutique fashion industry.

A strong visual arts community also lives in Dunedin and its environs, notably in Port Chalmers and the other settlements which dot the coast of the Otago Harbour, and also in communities such as Waitati.

The climate of Dunedin in general is temperate, however the city is recognised as having a large number of microclimates and the weather conditions often vary between suburbs mostly due to the city's topographical layout.

It is also greatly modified by its proximity to the ocean. This leads to warm summers and cool winters.

Winter can be frosty, but significant snowfall is uncommon, except in the inland hill suburbs such as Halfway Bush and Wakari, which tend to receive a few days of snowfall each year.

Spring can feature "four seasons in a day" weather, but from November to April it is generally settled and mild. Temperatures during summer can top 30 °C (86 °F), but temperatures in the high 30s are rare.

Dunedin has relatively low rainfall in comparison to many of New Zealand's cities.
