Buckton Castle is a medieval ringwork near Carrbrook, Stalybridge, England. It is listed as a Scheduled Ancient Monument due to its proximity to the Buckton Vale Quarry. The castle is oval, with a stone curtain wall wide, surrounded by a ditch wide and deep. Buckton Castle was probably constructed for William de Neville in the late 12th century; it was lying derelict by 1360. The small number of finds retrieved during archaeological investigation of the site indicates that Buckton Castle may not have been completed.
