This is a list of the 53 Grade I listed buildings in Monmouthshire, Wales.[1]

In the United Kingdom, the term "listed building" refers to a building or other structure officially designated as being of special architectural, historical or cultural significance. These buildings are in three grades: Grade I consists of buildings of outstanding architectural or historical interest. Listing was begun by a provision in the Town and Country Planning Act 1947. Once listed, strict limitations are imposed on the modifications allowed to a building's structure or fittings. In Wales,[2] the authority for listing under the Planning (Listed Buildings and Conservation Areas) Act 1990[3] rests with Cadw.
