Sedgefield District was, from 1974 to 2009, a local government district and (from 1996), borough in County Durham, in North East England. It had a population of about 87,000 (2001 UK census). It was named after Sedgefield, but its largest town was Newton Aycliffe. Other places included Shildon, Ferryhill and Spennymoor.

The borough was formed (as Sedgefield District), in 1974, under the Local Government Act 1972, by the merger of Sedgefield Rural District, Spennymoor and Shildon urban districts and part of Darlington Rural District.

The borough was abolished as part of the 2009 structural changes to local government in England.

From 1983 to 2007, most of the district was represented in parliament by Tony Blair, who became Leader of the Labour Party in 1994, and Prime Minister in 1997.
