The Dunedin Botanic Garden (usually locally known in the plural form as the Dunedin Botanic Gardens) is located at the northern end of central Dunedin, in the South Island of New Zealand. The garden is close to the University of Otago and one of the city's most historic cemeteries, the Northern Cemetery, on a spur of Signal Hill and on the river plain immediately below it. These two parts of the gardens are known simply as the upper gardens and the lower gardens.
