South Dunedin is a major inner city suburb of the New Zealand city of Dunedin. It is located, as its name suggests, 2.5 kilometres (1.6 mi) to the south of the city centre, on part of a large plain known locally simply as "The Flat". The suburb is a mix of industrial, retail, and predominantly lower-quality residential properties. South Dunedin's 2006 population was 2,490, a decrease of 48 people from 2001.
