Romantic painting by Charles Gleyre (19th century) celebrating the Tigurini victory over the Romans at [[Agen (107 BC) under Divico's command.]] thumb|Julius Caesar and Divico parley after the battle at the Saône. Historic painting of the 19th century by [[Karl Jauslin.]] Divico was a Celtic king and the leader of the Helvetian tribe of the Tigurini. During the Cimbrian War, in which the Cimbri and Teutons invaded the Roman Republic, he led the Tigurini across the Rhine to invade Gaul in 109 BC. He defeated a Roman army near present-day Agen on the Garonne river at the Battle of Burdigala in 107 BC, killing its leaders Lucius Cassius Longinus, the Roman consul, and Lucius Calpurnius Piso Caesoninus. Eventually he led his people back to the tribes of the Helvetii, near present-day Switzerland where they settled in the Jura Mountains near Lac Leman. 49 years later, before the Battle of Bibracte, he led a delegation back to Gaul to negotiate for a safe passage for his tribe through the Roman region of Provence. The request was denied by Caesar who wanted revenge for a relative who had been killed in the battle near Agen in 107 BC.

He is not to be confused with the military and religious leader of another gaulish tribe, Diviciacus of the Aedui.
