Oaro is a settlement close to the Pacific Ocean Coast of north Canterbury, in the South Island of New Zealand.

Oaro is within Kaikōura District on State Highway 1 and on the South Island Main Trunk railway, 20 kilometres south of Kaikōura.

The headland of Piripaua (Spyglass Point) and the associated Haumuri Bluff are located just to the south of the settlement.

[4] Alternatively it could mean "The place of Aro", which may have been the name of a prominent local Māori individual.

The area around Oaro was badly affected by the 2016 Kaikōura earthquake.
