The Royal Commission on the Ancient and Historical Monuments of Wales (RCAHMW; Welsh: Comisiwn Brenhinol Henebion Cymru; CBHC), established in 1908, is a Welsh Government sponsored body concerned with some aspects of the archaeological, architectural and historic environment of Wales. It is based in Aberystwyth. The RCAHMW maintains and curates the National Monuments Record of Wales (NMRW), an archive with an online platform called Coflein. Professor Nancy Edwards is Chair of the Commissioners.
