Tottenham House is a large Grade I listed English country house in the parish of Great Bedwyn, Wiltshire, about five miles southeast of the town of Marlborough. It is separated from the town by Savernake Forest, which is part of the Tottenham Park estate.
The site of the house was part of the much larger Savernake Forest, and in the Middle Ages was controlled by the heads of the Esturmy family. In the 15th century, the land passed by marriage to the House of Seymour of nearby Wulfhall, about one mile to the south. The original house was probably built in about 1575 by Edward Seymour, 1st Earl of Hertford, a nephew of Queen Jane Seymour, when it was known as Totnam Lodge. The present house incorporates parts of the earlier houses on the site built by the Seymours. In 1675, the estate passed to Lady Elizabeth Seymour, who married Thomas Bruce, 2nd Earl of Ailesbury, thus bringing the house into the Bruce family.
