Pascweten (died 876) was the count of Vannes and a claimant to the rule of Brittany. He was a son of Ridoredh of Vannes, a prominent and wealthy aristocrat first associated with the court of Erispoe in the 850s. He owned vast landed estates and salt works (as at Guérande) in southeastern Brittany and was a patron of Redon Abbey.
Pascweten was a son-in-law of Salomon, Duke of Brittany, in August 867, when he negotiated a lasting peace at Compiègne with Charles the Bald on behalf of his father-in-law and prevented the king from marching on Brittany. Pascweten swore an oath of fidelity to Charles on Salomon's behalf.
