St Botolph's Church is the Church of England parish church of Hardham, West Sussex. It is in Horsham District and is a Grade I listed building. It contains the earliest nearly complete series of wall paintings in England. Among forty individual subjects is the earliest known representation of St George in England. Dating from the 12th century, they were hidden from view until uncovered in 1866 and now "provide a rare and memorable impression of a medieval painted interior". The simple two-cell stone building, with its original medieval whitewashed exterior, has seen little alteration and also has an ancient bell.

Botolph of Thorney was an English abbot and saint. He is regarded as the patron saint of boundaries, and by extension, of trade and travel, as well as various aspects of farming. His feast day is celebrated either on 17 June (England) or 25 June (Scotland).
