The Urdd National Eisteddfod is an annual Welsh-language youth festival of literature, music and performing arts organised by Urdd Gobaith Cymru.

Arguably Europe’s largest youth festival, it is usually held during the last week of May, coinciding with schools’ half term holiday. Locations alternate between north and south Wales. The Eisteddfod consists of competitive singing, recitation, art, composition, dance and instrumental events for contestants aged between 7 and 24 years. Regional qualifying heats are held in advance around Wales, as occurs for the National Eisteddfod. Afanti televises 110 hours live of the Urdd every year.
