Tasman District

 is a local government region of New Zealand. It adjoins the northern corner of the coast of the South Island, the West Coast Region to the west, the Nelson Region to the north-east, and the Marlborough Region to the east.

The region comprises only the Tasman District, and the Tasman District Council is the unitary authority. Chief population centres are Richmond (the "county seat", on the fringe of Nelson City) and Motueka. Others include Takaka and Murchison.

The region is entirely within the former Nelson Province (1852-1876).
