Havelock is a small town in the Marlborough Region of New Zealand, at the head of Pelorus Sound, one of the Marlborough Sounds, and at the mouth of the Pelorus and Kaituna Rivers State Highway 6 from Nelson to Blenheim passes through the town.

Queen Charlotte Drive, which provides a shorter but very winding road to Picton proceeds east along the edge of the Sounds.

[7] The gold rush to the Wakamarina Valley in 1864 boosted the growth of the township, with sawmilling becoming the main activity until the 1910s, later joined by dairying.

Across the Kaituna River estuary, the Cullen Point Scenic Reserve[8] and the Mahakipawa Hill Scenic Reserve[9] offer a coastal walking-track to a lookout at Cullen Point.

It is part of the larger Marlborough Sounds West statistical area.

Before the 2023 census, the settlement had a smaller boundary, covering 1.67 km2 (0.64 sq mi).

[10] Marlborough Sounds West, which also includes Rai Valley and Ōkiwi Bay, covers 1,557.89 km2 (601.50 sq mi)[1] and had an estimated population of 2,230 as of June 2024,[11] with a population density of 1.4 people per km2.
