The Vanguard Way is a long distance walk of around 66 miles from East Croydon in outer London to Newhaven on the south coast of England. It passes through the counties of Surrey, Kent and East Sussex, between Croydon and Newhaven, East Sussex. It connects the London suburbs to the south coast, via the North Downs, Ashdown Forest, South Downs National Park and the Cuckmere valley.

The walk was developed in celebration of the 15th anniversary in 1980 of the Vanguards Rambling Club, who named themselves after an occasion when they returned from a walk travelling in the guard's van of a crowded train.

The Vanguard Way connects with central London with the Wandle trail along the river Wandle from Croydon and is sometimes used as a walking route between London and Paris, connecting with the ferry ports on the south coast. The walk also connects with the London Outer Orbital Path, North Downs Way, Greensand Way, London Countryway, Eden Valley Walk, Forest Way, Wealdway, Sussex Border Path and the South Downs Way.
