The A235 is a non-primary A road between Purley and Thornton Heath in the London Borough of Croydon. Before the construction of the Purley Way (Croydon bypass) in the 1920s, it was part of the A23 London to Brighton road.

The northern (London Road) part of the road is used by many bus routes to reach Central London and Brixton: Mayday University Hospital is on the road as is the old Safari Cinema. Whitgift School is on the southern (Brighton Road) stretch.
