The Senones (Ancient Greek: Σήνωνες) were an ancient Celtic Gallic culture.
They joined Bellovesus' migrations towards Italy, together with the Aeduii, Ambarri, Arverni, Aulerci, Carnutes and Senones.
In the year of 400 BC they crossed the Alps and, driving out the Umbrians settled on the east coast of Italy from Forlì to Ancona, in the Ager Gallicus, and founded the town of Sena Gallica (Senigallia), which became their capital. In 391 BC, under the chieftain Brennus, they invaded Etruria and besieged Clusium. The Clusines appealed to Rome, whose intervention, accompanied by a violation of the law of nations, led to war, the defeat of the Romans at the Battle of the Allia (18 July 390BC) and the sacking of Rome.
