Clayton Hall is a 15th-century manor house on Ashton New Road in Clayton, Manchester, England, hidden behind trees in a small park. The hall is a Grade II* listed building, the mound on which it is built is a scheduled ancient monument, and a rare example of a medieval moated site. The hall is surrounded by a moat, making an island 66 by 74 metres. Alterations were made to the hall in the 16th and 17th centuries, and it was enlarged in the 18th century.
