Rhuddlan (Welsh pronunciation: [ˈr̥ɨðlan], approximately "RITH-lan") is a town and community in the county of Denbighshire within the historic boundaries of Flintshire, in north Wales. It is situated to the south of the coastal town of Rhyl and overlooks the River Clwyd. The town gave its name to the Welsh district of Rhuddlan from 1974 to 1996. At the 2001 Census, the population was 4,296.
Rhuddlan has a longer history than the castle fortress built following Edward I of England's Conquest of Wales. Prior to Norman occupation of lower Gwynedd, the Perfeddwlad, Rhuddlan was the site of a Welsh cantref and served as the seat of government for the Welsh king Gruffydd ap Llywelyn (1007 – August 5, 1063), whose family may have been the traditional Welsh lords of Rhuddlan for generations.
In 2001, the A525 bypass road was completed, easing access to Rhyl, and since then the centre of Rhuddlan has been redeveloped.
Notable people 
Photographer Philip Jones Griffiths, well known for his photographs during the Vietnam War, was born in Rhuddlan. Wales and Sunderland FC footballer David Vaughan was also born in the town. Lisa Scott-Lee of the pop band Steps and her brother Andy Scott-Lee lived in Rhuddlan.
Rhuddlan Community Recycling Centre 
Denbighshire County Council's (DCC) recent controversial plans to build a recycling centre off the A525, to the south of Rhuddlan, have been scrapped.
The local council faced very strong, and very public, condemnation of their plans from Rhuddlan's residents, Professor David Bellamy and CADW. The council said that it would not be submitting any further planning applications for the site and that it would be restored to its former condition. Local residents have proposed that the site be turned into an environment and nature park.
