St Peter's Church is the Church of England parish church of the parish of Ardingly in Mid Sussex, one of seven local government districts in the English county of West Sussex. The present building dates from the 14th century and was restored during the Victorian era, but Christian worship on the site has a much longer history. The stone-built, Decorated Gothic-style church, west of the village centre, has been listed at Grade I by English Heritage for its architectural and historical importance.
