Taliesin was an early Brittonic poet of Sub-Roman Britain whose work has possibly survived in a Middle Welsh manuscript, the Book of Taliesin. Taliesin was a renowned bard who is believed to have sung at the courts of at least three kings.

Sub-Roman Britain is the period of late antiquity in Great Britain between the end of Roman rule and the Anglo-Saxon settlement. The term was originally used to describe archaeological remains found in 5th- and 6th-century AD sites that hinted at the decay of locally made wares from a previous higher standard under the Roman Empire. It is now used to describe the period that commenced with the recall of Roman troops to Gaul by Constantine III in 407 and to have concluded with the Battle of Deorham in 577.
