Cemaes is a village on the north coast of Anglesey in Wales, sited on Cemaes Bay, an Area of Outstanding Natural Beauty which is partly owned by the National Trust. It is the most northerly village in Wales (excluding the nearby hamlet of Llanbadrig). The name Cemaes was originally spelt Cei Maes meaning Field Quay, but over the years the "i" has been dropped. In 2011 the population of Cemaes (Llanbadrig ward) was 1,357.
