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.

Sudbrook and its tributary, the Latchmere stream, are north-flowing streams in London, England, that drain northern Kingston upon Thames and the eastern extreme of Ham following a meander scar in a terrace; the upper part of the Sudbrook drains a narrow vale in Richmond Park's southern corner into the tidal Thames.
