Rhuddlan (Welsh pronunciation: [ˈr̥ɨðlan] ) is a town, community, and electoral ward in the county of Denbighshire, Wales, in the historic county of Flintshire. Its associated urban zone is mainly on the right bank of the Clwyd; it is directly south of seafront town Rhyl. It gave its name to the Welsh district of Rhuddlan from 1974 to 1996. As of the 2001 census, the population was 4,296  decreasing to 3,709 in the 2011 census. 
The name of the town is a combination of the Welsh words rhudd "red" + glan "riverbank". 
In AD 921, the Anglo-Saxon king, Edward the Elder, founded a burh named Cledematha at Rhuddlan.  In the following century, before the Norman Conquest and subsequent Norman occupation of lower Gwynedd, the Perfeddwlad, Rhuddlan was the site of a Welsh cantref and served as the seat of government and capital of Gwynedd for the Welsh king Gruffydd ap Llywelyn (ruled 1055 – 1063), whose family may have been the traditional Welsh lords of Rhuddlan for generations.[ citation needed ] Following the Conquest, in 1086, Rhuddlan was recorded in the Domesday Book as a small settlement within the hundred of Ati's Cross and in the county of Cheshire. 
A mint established at Rhuddlan in the 1180s by Dafydd ab Owain, and later maintained by Llywelyn the Great, was responsible for minting the first native Welsh coinage since the reign of Hywel Dda.
The town is known for the ruins of Rhuddlan Castle, built by order of King Edward I from 1277 to 1282, and for the site of another castle at Twthill, built by the Norman Robert of Rhuddlan about 1072. Well-preserved Rhuddlan castle has a great round tower and many surviving walls. It was built soon after the conquest of Wales.
The town was thus where Edward I signed the Statute of Rhuddlan, laying down the way by which the Principality of Wales, created by the princes of Gwynedd, was to be governed.
The town's first Welsh chapel, now 17 Cross Street, was built in 1771. 
The hymn tune "Rhuddlan" was brought to wider prominence by Ralph Vaughan Williams as music editor of the first edition of The English Hymnal in 1906, and it has since been adopted by numerous other hymnals. It is usually sung to the words of the hymns "Judge eternal, throned in splendour" and, more recently, "For the healing of the nations".
Rhuddlan railway station was part of the Vale of Clwyd Railway. The station closed in 1955 but the line remained open until 1968. The station was demolished around 1977 and a Premier Inn now occupies the site. 
In 2001, the A525 bypass was completed, easing access to Rhyl. Since 2001 the centre of Rhuddlan has been largely redeveloped.
In 2021 February, archaeologists from Aeon Archaeology announced the discovery of more than 300 stone age tools and artefacts in Rhuddlan. They revealed scrapers, microliths, flakes of chert (hard, sedimentary rock), flints and even rudimentary tools. Expert Richard Cooke believes that the remains were belong to people who was passing through and made camp by the river more than 9,000 years ago.

The history of Gwynedd in the High Middle Ages is a period in the History of Wales spanning the 11th through the 13th centuries. Gwynedd, located in the north of Wales, eventually became the most dominant of Welsh polities during this period. Contact with continental courts allowed for Gwynedd to transition from a petty kingdom into an increasingly sophisticated principality of seasoned courtiers capable of high level deplomacy and representation; not only with the Angevine kings, but also the king of France and the Papal See. Distinctive achievements in Gwynedd include further development of Medieval Welsh literature, particularly poets known as the Beirdd y Tywysogion associated with the court of Gwynedd; the reformation of bardic schools; and the continued development of Cyfraith Hywel. All three of these further contributed to the development of a Welsh national identity in the face of Anglo-Norman encroachment of Wales.
The conquest of Wales by Edward I took place between 1277 and 1283. It is sometimes referred to as the Edwardian Conquest of Wales, to distinguish it from the earlier Norman conquest of Wales. In two campaigns, in 1277 and 1282–83, respectively, Edward I of England first greatly reduced the territory of Llywelyn ap Gruffudd, and then completely overran it, as well as the other remaining Welsh principalities.
