Harwood is a rural settlement on the northern side of the Otago Peninsula. It is within the boundaries of Dunedin city in New Zealand.

Before 2000, most of the houses were cribs, but they have since been upgraded and become permanent residences.

The area is named for Octavius Harwood and his family, who moved here from Otakou in the 1870s and farmed cattle.
