Venutius was a 1st-century king of the Brigantes in northern Britain at the time of the Roman conquest. Some have suggested he may have belonged to the Carvetii, a tribe that probably formed part of the Brigantes confederation. Taking advantage of Roman instability during the year of four emperors, Venutius revolted again, this time in 69 AD. Cartimandua appealed for troops from the Romans, who were only able to send auxiliaries. Cartimandua was evacuated and Venutius took the kingdom.
