This list of scheduled monuments in the City of Milton Keynes lists the 49 scheduled monuments in the part of Buckinghamshire administered by Milton Keynes City Council.
A scheduled monument is a nationally important archaeological site or monument which is given legal protection by being placed on a list (or "schedule") by the Secretary of State for Culture, Media and Sport; English Heritage takes the leading role in identifying such sites. The current legislation governing this is the Ancient Monuments and Archaeological Areas Act 1979. The term "monument" can apply to the whole range of archaeological sites, and they are not always visible above ground. Such sites have to have been deliberately constructed by human activity. They range from prehistoric standing stones and burial sites, through Roman remains and medieval structures such as castles and monasteries, to later structures such as industrial sites and buildings constructed for the World Wars or the Cold War.
