Whitwell is a village in the parish of St Paul's Walden about six miles south of Hitchin in Hertfordshire, England. Situated on a tableland, a spur of the Chilterns, Whitwell is about 400 feet above sea level. The soil is mostly clay with flints.
It contains a number of early brick and half-timbered houses, several of which are of the 18th century. Local attractions include Waterhall Farm (an open farm and craft centre), and two country pubs, The Bull Inn and The Maidens Head. With the River Mimram running north-west to south-east through Whitwell, the village has been noted (apparently since Roman times) for its production of prime watercress.
Roman coins have been found in Whitwell.
Whitwell AFC, the village football club, was established in 1908 and currently play in the Hertfordshire Senior County League, winners of the 1st Division Championship in the 2011-12 season.
