Koolpinyah, Northern Territory

Koolpinyah  is a locality in the Northern Territory of Australia located about 37 km east of the territory capital of Darwin.

The locality consists of land bounded to the east by the Adelaide River and in part to the north by the Clarence Strait. This locality is named after Koolpinyah Station, a pastoral lease established on land now partly included in the locality in 1908 by Evan and Oscar Herbert, the sons of Charles Edward Herbert, a judge, a politician and a former Government Resident of the Northern Territory. The name is ultimately derived from "Gulpinyah", the aboriginal name for a waterhole located near the station’s homestead. Its boundaries and name were gazetted on 4 April 2007.

The 2016 Australian census which was conducted in August 2016 reports that Koolpinyah had no people living within its boundaries.

Koolpinyah is located within the federal division of Lingiari, the territory electoral division of Goyder and within the local government area of the Litchfield Municipality.
