Clapham Wood is a woodland area in the South Downs National Park near the village of Clapham, West Sussex, England. It is a designated Site of Nature Conservation Interest (SNCI) composed of ancient, semi-natural woodland with rich flora and fauna. It is a popular location for walkers in easy reach from nearby Durrington and Worthing and is well provided with wide paths through the mixed and coppiced woodland. The southern parts of the woodland are popular in the spring, with extensive carpets of bluebells growing close to the paths. There are views of the English Channel to the south, and of the dry valley Long Furlong, with Blackpatch Hill and long barrows beyond, to the north.
