Biddesden House is a Grade I listed house in the parish of Ludgershall, Wiltshire and near to Andover in Hampshire. It is home to an Arabian Horse stud farm.
The house belonged to John Richmond Webb from 1692, and passed to other owners before being bought by Bryan Guinness in the 1930s, whose family still live there.
The stud bred the eventing champion Tamarillo.
