The First Battle of Bedriacum, also known as the First Battle of Cremona, was a military engagement fought on 14 April AD 69 between the forces of Otho and Vitellius, two rival claimants to the throne of the Roman Empire during the Year of the Four Emperors that followed the deaths of Nero and Galba. It took place near Bedriacum (modern Calvatone), about 35 km from Cremona in what is now Lombardy. Because the action was fought between the two towns, the battle is known by both names.
The defeat of Otho's forces effectively decided the brief civil war between the two emperors. On hearing the news Otho took his own life two days later, while Vitellius continued his march on Rome and was acknowledged emperor by the Senate.
