Musselburgh is a residential 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, and at the narrowest point of the isthmus which joins Otago Peninsula to the rest of the South Island (here just 1.5 kilometres (0.93 mi) in width). The suburb takes its name from the similarly named town in Scotland. Musselburgh's 2001 population was 2,835.
