The A217 is a road in London and Surrey in England. It runs north–south. It runs from Kings Road in Fulham, London, crosses the Thames at Wandsworth Bridge, then passes through Wandsworth, Earlsfield, Summerstown, Tooting, Mitcham, Rosehill and Sutton Common in Sutton, then Cheam. Then, widened as a dual carriageway, comes Belmont, a suburban district built on a slope rising southward. On the North Downs in Surrey the road then skirts past Banstead and through its late 19th century offspring villages particularly Burgh Heath and Kingswood, Surrey. It then crosses the M25 motorway at Junction 8, then, returning to single carriageways, passes through the castle town of Reigate. It then cuts through the green buffer farmland of two rural villages and terminates at the road network at Gatwick Airport's northern perimeter.

Wandsworth Bridge crosses the River Thames in west London. It carries the A217 road between the area of Battersea, near Wandsworth Town Station, in the London Borough of Wandsworth on the south of the river, and the areas of Sands End and Parsons Green, in the London Borough of Hammersmith and Fulham, on the north side.
