Dean of Llandaff is the title given to the head of the chapter of Llandaff Cathedral, which is located in Llandaff, Cardiff, Wales. It is not an ancient office – the head of the chapter was historically the Archdeacon who appears in this role in the Liber Landavensis and in the Chapter Acts preserved in the Glamorgan Records Office – but the title of Dean was established in 1843. A century later the Deanery was merged with the Vicarage of Llandaff. The Chapter forfeited its legal rights on Disestablishment in 1920. The Dean since 2000 has been John Lewis.
