The Shire of Northampton is a local government area in the Mid West region of Western Australia, about 50 kilometres (30 mi) north of Geraldton and about 460 kilometres (290 mi) north of the state capital, Perth. The Shire covers an area of 13,738 square kilometres (5,304 sq mi), and its seat of government is the town of Northampton, with the largest settlement being Kalbarri.

The shire includes the former Principality of Hutt River, a now dissolved micronation which has no recognition by the state or federal governments.

The Mines Road District was constituted on 25 January 1871 under the Road Boards Act 1871. It was renamed the Northampton Road District on 10 February 1887. On 1 July 1961, it became a shire following the passage of the Local Government Act 1960, which reformed all remaining road districts into shires.^[3]

The Shire is divided into six wards, most of which elect one councillor:

• Kalbarri Ward (four councillors)
• Central Ward (three councillors)
• Coastal Ward
• North East Ward
• South East Ward
• West Ward

Prior to May 2003, the Coastal Ward was known as the Horrocks Ward, the Kalbarri Ward had three councillors and all the others had two councillors.^[4]
