Ottershaw is a village in the Borough of Runnymede in Surrey, England, approximately 32 km (20 mi) southwest of central London.

Its nearest passenger trains to London leave from Addlestone railway station, centred 2.5 miles (4.0 km) east, on a branch line, with two others on a main line a slightly greater distance to the south —; the principal one which has frequent, semi-fast services to London being West Byfleet.

The Ottershaw Society has carried out a comparative, now and then, survey of the village comprising more than 1,000 images (photographs and illustrations) from the mid-19th century to the present time, older residents' memories and various other historical written material.

The adult development side play in Guildford & Woking Alliance League Division 1.

In the book The War of the Worlds by H. G. Wells, the fictional narrator is invited to an observatory in Ottershaw.
