Winnold House, formerly the Benedictine Priory of St Winwaloe, is a country house in the parish of Wereham in Norfolk, England. The house is constructed from the remaining fragments of a former Benedictine priory. The priory was founded in 1199 and was dissolved in 1321. It was demolished in 1539, and the surviving fragments were incorporated into a house sometime in the 17th century; it was rebuilt in the mid-19th century. It is a Grade II* listed building.
