The Chairing of the Bard is one of the most important events in the Welsh eisteddfod tradition. The most famous chairing ceremony takes place at the National Eisteddfod of Wales, and is always on the Friday afternoon of Eisteddfod week. Winners are referred to as Y Prifardd. The custom of chairing the bard is, however, much older than the modern eisteddfod ceremony, and is known to have taken place as early as 1176.

The National Eisteddfod of Wales is the largest of several eisteddfodau that are held annually, mostly in Wales. Its eight days of competitions and performances are considered the largest music and poetry festival in Europe. Competitors typically number 6,000 or more, and overall attendance generally exceeds 100,000 visitors, the highest recently being 118,000 attending the 2022 festival. The 2018 Eisteddfod was held in Cardiff Bay with a fence-free 'Maes'. In 2020, the event was held virtually under the name AmGen; events were held over a one-week period.
