Havelock is a coastal village in the Marlborough region of New Zealand. It sits at the head of Pelorus Sound, one of the Marlborough Sounds. The population was 486 in the 2006 Census, an increase of 12 from 2001. State Highway 6 from Nelson to Blenheim passes through the town. Queen Charlotte Drive, which provides a shorter but very tortuous road to Picton proceeds east along the edge of the Sounds.
Canvastown is 10 km to the west. Renwick is 31 km to the south. Picton is 35 km to the east. Havelock is the centre for much of the New Zealand green-lipped mussel industry, and is called the greenshell mussel capital of the World. Havelock was named after Sir Henry Havelock, known from the Siege of Lucknow during the Indian Rebellion of 1857. The main street is Lucknow Street.
