Ham House is a 17th-century house set in formal gardens on the bank of the River Thames in Ham, south of Richmond in the London Borough of Richmond upon Thames. The original house was completed in 1610 by Thomas Vavasour, an Elizabethan courtier and Knight Marshal to James I. It was then leased, and later bought, by William Murray, a close friend and supporter of Charles I. The English Civil War saw the house and much of the estate sequestrated, but Murray's wife Katherine regained them on payment of a fine. During the Protectorate his daughter Elizabeth, Countess of Dysart on her father's death in 1655, successfully navigated the prevailing anti-royalist sentiment and retained control of the estate.

Ham is a suburban district in Richmond, south-west London. It has meadows adjoining the River Thames where the Thames Path National Trail also runs. Most of Ham is in the London Borough of Richmond upon Thames and, chiefly, within the ward of Ham, Petersham and Richmond Riverside; the rest is in the Royal Borough of Kingston upon Thames. The district has modest convenience shops and amenities, including a petrol station and several pubs, but its commerce is subsidiary to the nearby regional-level economic centre of Kingston upon Thames.
