House Copse is a 12.5-hectare (31-acre) biological Site of Special Scientific Interest west of Crawley in West Sussex.

This ancient wood was formerly managed as hornbeam and small-leaved lime coppice with oak standards. There is limited ground flora in densely shaded areas, but the banks of a stream have more diverse flora, including dog’s mercury, wood avens, bugle and enchanter’s nightshade.

The site is private land with no public access.
