Corstorphine is a suburb of southwest Dunedin in the South Island of New Zealand. It is located on the slopes of Calton Hill - a spur of Forbury Hill - between Caversham Valley and the Pacific Ocean. The suburbs of Saint Clair and Forbury lie to the east and south, and Caversham and Lookout Point lie to the north.

Caversham is one of the older suburbs (neighbourhoods) of the city of Dunedin, in New Zealand's South Island. It is sited at the western edge of the city's central plain at the mouth of the steep Caversham Valley, which rises to the saddle of Lookout Point. Major road and rail routes south lie nearby; the South Island Main Trunk railway runs through the suburb, and a bypass skirts its main retail area, connecting Dunedin's one-way street system with the Dunedin Southern Motorway. The suburb is linked by several bus routes to its neighbouring suburbs and central Dunedin.
