Roseneath, Otago

Roseneath is a small suburb of the New Zealand city of Dunedin, located on the northwestern shore of Otago Harbour, 12 km to the northeast of Dunedin city centre. It is situated between Saint Leonards and Port Chalmers on a rocky promontory of the same name which juts 0.6 km into the harbour between Sawyers Bay and Blanket Bay. The suburb and promontory are likely to have been named from the similar location of Rosneath in Scotland.

State Highway 88, linking Port Chalmers and central Dunedin traverses a low saddle immediately to the west of the suburb, and the South Island Main Trunk rail line passes through a tunnel beneath the promontory. The suburb's few streets include District Road, Shandon Street, and Clyde Street. Panoramic views of the harbour can be gained from close to the short peninsula's southernmost point, Kilgour Point.

Prior to local body reorganisation in New Zealand in the late 1980s, Roseneath was a suburb of Port Chalmers.
