Nanpean (from Cornish: Nanspian, meaning "little valley") is a village in the civil parish of St Stephen-in-Brannel in Cornwall, United Kingdom. The B3279 road runs through the village which is approximately 4 miles (6.4 km) north-west of St Austell in the heart of 'clay country', the china clay mining area of mid-Cornwall. There are plans to build 150–300 homes as part of the St Austell and Clay Country Eco-town. The plan was given outline approval in July 2009.
