Peltuinum was a Roman town of the Vestini, on the ancient Via Claudia Nova, 20 km east of L'Aquila, Italy, between the modern-day settlements of Prata d'Ansidonia and Castelnuovo. It was apparently the chief town of that portion of the Vestini who dwelt west of the main Apennine chain. Remains of the town walls, of an amphitheatre, of a temple and of other buildings still exist.
