Bilsham Chapel is a deconsecrated former chapel in the hamlet of Bilsham in West Sussex, England. Founded in the 13th century as a chapel of ease to the parish church of Yapton, the nearest village, the small flint building fell out of religious use around the time of the Reformation. It has subsequently been used for storage and as labourers' cottages, and since 1972 it has been a single residential property. English Heritage has listed it at Grade II for its architectural and historical importance.
