Tilford is a village and civil parish centred at the point where the two branches of the River Wey merge in Surrey, England, 3 miles (4.8 km) south-east of Farnham. It has half of Charleshill, Elstead in its east, a steep northern outcrop of the Greensand Ridge at Crooksbury Hill on Crooksbury Common in the north and Farnham Common (woodland) Nature Reserve in the west, which has the Rural Life Living Museum. As the Greensand Ridge in its western section is in two parts, the Greensand Way has a connecting spur here to its main route running east–west to the south.

The River Wey is a main tributary of the River Thames in south east England. Its two branches, one of which rises near Alton in Hampshire and the other in West Sussex to the south of Haslemere, join at Tilford in Surrey. Once combined, the flow is eastwards then northwards via Godalming and Guildford to meet the Thames at Weybridge. Downstream the river forms the backdrop to Newark Priory and Brooklands. The Wey and Godalming Navigations were built in the 17th and 18th centuries, to create a navigable route from Godalming to the Thames.
