Marlborough region

 is a local government region of New Zealand. It adjoins the eastern corner of the coast of the South Island, the Nelson Region to the north-west, the Tasman Region to the west, and the Canterbury Region to the south.

The region comprises only the Marlborough District, and the Marlborough District Council is the unitary authority. Chief population centres are Blenheim (the "county seat"), with Renwick 12 km west, and the major ferry terminal Picton. Others include Havelock, Ward, and Seddon.

The region is largely the same as the former Marlborough Province (1859-1876) with the exclusion of the Kaikoura District in the south. It produces world-class sauvignon blanc grapes.
