Westland County, also known as County of Westland, was a local government area on the West Coast of New Zealand's South Island. It existed from 1868 to 1873, and then from 1876 until 1989. In its first incarnation it constituted the government for the area that was split from the Canterbury Province, with the West Coast Gold Rush having given the impetus for that split. It had the same administrative powers as a provincial council, but the legislative power rested with Parliament in Wellington. The first Westland County was the predecessor to Westland Province.
