Thanington is a civil parish on the west edge of Canterbury, Kent, United Kingdom.

It extends to the south-west of A2 from Wincheap to the Milton Bridge in Chartham.

The north ward of Thanington Without follows the River Stour nearest to the city centre and London railway line, it has private housing north of Ashford Road and a large estate of mixed housing south of Ashford Road.

Previously (since the A2 Canterbury bypass was constructed in the early 1980s), the two slip roads at Thanington were east-facing and led only to and from Dover.

In 2006, the Government, the Highways Agency, Kent County Council and Canterbury City Council agreed that adding the two west-facing slip-roads would help to ease the traffic congestion in Wincheap between the Westgate and the A2.
