Kimmeridge is a small village in the English county of Dorset. It is situated just over half a mile (1 km) inland on the Isle of Purbeck on the English Channel coast, south of Wareham and about west of Swanage. It lies within the Purbeck administrative district of the county, and has a population of 110 (2001).
On the coast south-west of the village lies the roughly semi-circular Kimmeridge Bay, which is backed by low cliffs of soft shale. Beneath the cliffs there is a large wave-cut platform (known as The Flats) and a rocky shore with rock pools and attendant ecology. Kimmeridge Bay is a surfer area.
