Andersons Bay (sometimes spelt in the grammatically correct former form Anderson's Bay, and often known locally simply as "Andy Bay") is a suburb of the New Zealand city of Dunedin. It is located in the southeast of the city's urban area, 2.8 kilometres (1.7 mi) southeast of the city's centre.
The suburb of Andersons Bay extends south from the Andersons Bay Inlet, an indentation in the southern shore of the Otago Harbour, and across the isthmus joining the Otago Peninsula to the mainland. In 2001 Andersons Bay had a population of 2,532.
The suburb's name is also occasionally used for the area extending north along the Southern Endowment, an area of land reclaimed from the harbour which sits close to its western shore - towards the suburb of South Dunedin. This area, which was reclaimed during the mid-twentieth century, was the location of the bay for which the suburb is named. The Southern Endowment, largely used for light industrial purposes, also includes a sports complex, the Edgar Centre.
South of the Anderson's Bay Inlet the suburb comprises residential housing. It is bounded by Musselburgh in the west and southwest, Shiel Hill in the east, and the coastal suburbs of Tahuna and Tainui in the south. These two smaller suburbs, which lie close to the Pacific Ocean, are often considered part of either Andersons Bay or Musselburgh. The rocky outcrops of the Musselburgh Rise stand immediately to the west and south of the Andersons Bay Inlet.
Close to the northern edge of the Andersons Bay Inlet a large memorial stone commemorates the Taranaki Māori prisoners of the New Zealand Land Wars who were transported south to Dunedin, many of whom constructed the causeway across the head of the inlet and much of Dunedin's foreshore roads as forced labour. A branch railway ran along Portobello Road in this area from the 1870s until 1912.
