Harpsden is a rural and semi-rural village and civil parish immediately south of Henley-on-Thames in South Oxfordshire, Oxfordshire, England. Its scattered centre is set 0.5 miles (0.80 km) from the east border which is the River Thames, marking a short boundary with Berkshire. The parish extends 5 miles (8.0 km) inland and borders Rotherfield Peppard to the west, that is, next to its main sections of woodland in the southern extreme of the Chiltern Hills including an SSSI area of ancient woodland. The village has neither a railway station nor shops, but has the main road from Reading to Henley, both of which have grown substantially since World War II into centres of trade, education and general meeting places, such as by their increased number of cafés and restaurants.

The nearest watercourse on the river map is the River Thames, about 30 m from the middle of Harpsden's gauges. It flows on to the sea.
A gauge downstream shows water that has already passed this point; one upstream sees it first. Distances along the river are from the point on the River Thames nearest the middle of Harpsden's gauges. From Ordnance Survey’s river map (OS Open Rivers), which leaves out small streams, ditches and culverts, so a nearer one may exist. This describes where water goes on the map; it says nothing about flooding at any address. Contains OS data © Crown copyright and database rights 2026.
