Gloucester Shire (/ˈɡlɒstər/ GLOST-ər) was a local government area in the Mid North Coast and Upper Hunter regions of New South Wales, Australia. The Shire was situated adjacent to the Bucketts Way and the North Coast railway line.

The last mayor of the Gloucester Shire Council was Cr. John Rosenbaum, an independent politician.

The Shire included the following towns and localities:

• Gloucester
• Gloucester Tops
• Barrington
• Barrington Tops
• Copeland
• Craven
• Stratford

A 2015 review of local government boundaries by the NSW Government Independent Pricing and Regulatory Tribunal recommended that the Gloucester Shire merge with adjoining councils. The government considered two proposals. The first proposed a merger of Gloucester Shire and Dungog Shire councils to form a new council with an area of 5,200 square kilometres (2,000 sq mi) and support a population of approximately 14,000. Following the lodging of an alternate proposal by Gloucester Shire Council to amalgamate the Gloucester, Great Lakes and Greater Taree councils, the NSW Minister for Local Government proposed a merger between the Dungog Shire and City of Maitland.

The council was dissolved on 12 May 2016 and the area included in the Mid-Coast Council, along with city of Greater Taree and Great Lakes Council.
