Greys Court is a Tudor country house and gardens in the southern Chiltern Hills at Rotherfield Greys, near Henley-on-Thames in the county of Oxfordshire, England. Now owned by the National Trust, it is located at grid reference SU725834, and is open to the public.
The name derives from an old connection to the Grey family, descendants of the Norman knight Anchetil de Greye. The estate or manor of Rotherfield Greys is referred to in the Domesday Book.
The mainly Tudor-style house has a courtyard and gardens. The walled gardens contain old-fashioned roses and wisteria, an ornamental vegetable garden, maze (laid to grass with brick paths, dedicated by Archbishop Robert Runcie on 12 October 1981) and ice house. Within its grounds are the fortified tower built circa 1347, the only remains of the medieval castle, overlooking the gardens and surrounding countryside, as well as a Tudor wheelhouse.
The house remains furnished as a family home, with some outstanding 18th-century plasterwork interiors.
