Cuthwine (born c. 565), was a member of the House of Wessex, the son of King Ceawlin of Wessex. Cuthwine's father Ceawlin was deposed from the throne of Wessex in 592 by his nephew Ceol. Therefore, Cuthwine never inherited the throne. Cuthwine went into exile for many decades, remaining a strong leader of the Saxons and passing on the royal line through his three sons.

The Chronicle depicts the battle as a major victory for Wessex's forces, led by Ceawlin and one Cuthwine, resulting in the capture of the Romano-British towns of Glevum (Gloucester), Corinium Dobunnorum (Cirencester), and Aquae Sulis (Bath).
