Basingwerk Abbey (Welsh: Abaty Dinas Basing) is a Grade I listed ruined abbey near Holywell, Flintshire, Wales. The abbey, which was founded in the 12th century, belonged to the Order of Cistercians. It maintained significant lands in the English county of Derbyshire. The abbey was abandoned and its assets sold following the Dissolution of the Monasteries in 1536.
The site is now managed by Cadw – the national Welsh heritage agency.
