Goat Island/Rakiriri is an island in Otago Harbour in Otago, in the southern South Island of New Zealand. It is located between Port Chalmers and Portobello, to the northeast of Dunedin's city centre. It has one of New Zealand's dual placenames. The Māori language portion "Rakiriri" was a significant name brought by the original settlers from their Pacific homelands, a simple translation being "Angry Sky (or Sky-father Rakinui)". The name is also sometimes used to refer to the extinct Dunedin Volcano, of which Otago Harbour is the crater.
