科罗曼德尔半岛（英语：Coromandel Peninsula）位于新西兰北岛中东部，长约110公里，平均宽31公里，西临泰晤士湾与豪拉基湾，东濒普伦蒂湾。半岛上耸立有摩艾豪岭和科罗曼德尔岭。1769年，詹姆斯·库克在科罗曼德尔半岛东部的墨丘利湾登陆，观察水星的运行轨道。位于普伦蒂湾岸边的惠蒂扬阿为半岛上最大的居民点。第二大定居点是位于西岸的科罗曼德尔，1852年曾在此发现金矿。

在19世纪的后半页，科罗曼德尔半岛上茂密的森林被有系统的砍伐，如今半岛上主要饲养绵羊和奶牛。旅游业发达。

The Coromandel Peninsula on the North Island of New Zealand extends 85 kilometres north from the western end of the Bay of Plenty, forming a natural barrier to protect the Hauraki Gulf and the Firth of Thames in the west from the Pacific Ocean to the east. At its broadest point, it is 40 kilometres wide. Almost the entire population lies on the narrow strips along the Hauraki Gulf and Bay of Plenty coasts. In fine weather the peninsula is clearly visible from Auckland, the country's biggest city, which lies on the far shore of the Hauraki Gulf, 55 kilometres to the west. The peninsula is part of the local government areas of Thames-Coromandel District and the Waikato Region.
