Burnside is a mainly industrial suburb of the New Zealand city of Dunedin. It is located at the mouth of a long valley, the Kaikorai Valley, through which flows the Kaikorai Stream. This valley stretches to the northeast for 3.5 kilometres (2.2 mi). Burnside is 5.5 kilometres (3.4 mi) to the southwest of the city centre, close to eastern end of the much larger suburb, Green Island. Other suburbs located nearby include Concord, immediately to the southeast and Kenmure further up Kaikorai Valley.
