Staffhurst Wood is a 51-hectare (130-acre) biological Site of Special Scientific Interest south of Oxted in Surrey. It is a Nature Conservation Review site, Grade 2. An area of 38.1 hectares (94 acres) is a Local Nature Reserve, which is owned by Surrey County Council.

This common on Weald Clay has been wooded since the Anglo-Saxon period and past management has left many ancient trees. The canopy is mainly pedunculate oak and the older trees support a rich lichen flora. The moth fauna is outstanding, with six uncommon species.

There is access from Staffhurst Wood Road.
