Stanmer Church is a former Anglican church in Stanmer village, on the northeastern edge of the English city of Brighton and Hove. The ancient village stands within Stanmer Park, the former private estate of the Earl of Chichester, which the Brighton Corporation acquired for the benefit of Brighton's citizens after the Second World War. The church and a stately home, Stanmer House, stand outside the village but within the park's boundaries. The church, which was declared redundant in 2008, has been listed at Grade II by English Heritage for its architectural and historical importance.
