The Borough of Ashford is a local government district with borough status in Kent, England which takes up the mid-east and a southern portion of the county. Its council is in the town of Ashford.
The borough was formed on 1 April 1974 by the merger of the borough of Tenterden with Ashford urban district, and the East Ashford, West Ashford and Tenterden Rural Districts. In geographical size it is the largest district in Kent.
Most of the area of the Borough is covered by fields and orchards, with a smaller portion of woodland, particularly on the fringes towards the North Downs and Greensand Ridge.
The Borough is divided into 39 civil parishes centred on villages, but the town of Ashford itself has experienced rapid urban growth leading to new suburbs such as Stanhope and Sevington. The corridor created by the M20 motorway and High Speed 1 and its railway station has led to agricultural land, particularly where it borders the town, being turned to urban uses. Consequently, the second most populous settlement today is Kennington, which is centred 1 mile (1.6 km) north of Ashford.
