The Battle of Ebro River was a naval battle fought near the mouth of Ebro River in the spring of 217 BCE between a Carthaginian fleet of approximately 40 quinqueremes, under the command of Himilco, and a Roman fleet of 55 ships, under Gnaeus Cornelius Scipio Calvus. Hasdrubal Barca, the Carthaginian commander in Iberia, had launched a joint expedition to destroy the Roman base north of the Ebro River. The Carthaginian naval contingent was totally defeated after a surprise attack by the Roman ships, losing 29 ships and the control of seas around Iberia. The reputation of the Romans was further enhanced in Iberia after this victory, causing rebellion among some of the Iberian tribes under Carthaginian control.
