The A25 road is an east–west main road in the South-East of England. Its carries traffic east from Guildford, Surrey, eastward through Surrey and into mid-west Kent, to the town of Sevenoaks, and then on to Wrotham Heath where it connects with the A20.

The A25 exits east from Guildford, soon crossing southwards over the North Downs at Newlands Corner, to run eastward below the southern edge of the North Downs, with the road's route alternating between the Vale of Holmesdale and the Greensand Ridge, passing through Dorking, Reigate, Redhill, Nutfield, Bletchingley, Godstone, Oxted, Westerham, Brasted, Sevenoaks and Borough Green. It crosses over the River Wey at Guildford, the River Mole at Dorking, the River Eden at Oxted, and the River Darent at Westerham. The A25 has junctions with several major London to south coast roads: the A24 at Dorking; the A23 at Redhill; the A22 at Godstone; and the A21 at Sevenoaks.

A short distance east of Borough Green, at Wrotham Heath, the A25 ends at a junction with the A20, which continues eastward towards Maidstone, and then south-east to Ashford, Folkestone, and then Dover. At its west end in Guildford, the A25 connects with the A3 which takes traffic towards Portsmouth on the south coast. Before leaving Guildford, the A3 connects the A25 with the A31, which continues the westward route to Farnham, before tracking south-westward to Winchester and Bournemouth.

The M25 motorway parallels the A25 between Reigate and Sevenoaks, with connections at Reigate, Godstone, and Sevenoaks. The M26 motorway parallels the A25 between Sevenoaks and Wrotham Heath.
