Cookstown District Council (Irish: Comhairle Cheantar na Coirre Críochaí; Ulster Scots: Districk Cooncil o Cookestoun) was a district council covering an area largely in County Tyrone and partly in County Londonderry. It merged with Dungannon and South Tyrone Borough Council and Magherafelt District Council in May 2015 under local government reorganisation in Northern Ireland to become Mid-Ulster District Council. Councillor Wilbert Buchanan of the Democratic Unionist Party was chairman in 2014/15. In elections for the Westminster Parliament it was part of Mid Ulster.
