The Statute of Rhuddlan (12 Edw 1 cc.1–12; ), also known as the Statutes of Wales () or as the Statute of Wales (), provided the constitutional basis for the government of the Principality of Wales from 1284 until 1536. The Statute introduced English common law to Wales, but also permitted the continuance of Welsh legal practices within the Principality. The Statute was superseded by the Laws in Wales Acts 1535 and 1542 when Henry VIII made Wales unequivocally part of the "realm of England".
