Cholmondeley Castle (/ˈtʃʌmlɪ/ CHUM-lee) is a country house in the civil parish of Cholmondeley, Cheshire, England. Together with its adjacent formal gardens it is surrounded by parkland. The site of the house has been a seat of the Cholmondeley family since the 12th century. The present house replaced a timber-framed hall nearby. It was built in the early 19th century for George Cholmondeley, 1st Marquess of Cholmondeley, who designed most of it himself in the form of a battlemented castle. After the death of the Marquess, the house was extended to designs by Robert Smirke to produce the building in its present form.
