The Battle of Sena Gálica was a battle that took place in April or May of 82 BC during the context of Sulla's Second Civil War in the area around present day Senigallia. The battle pitted the Optimates under the command of Gnaeus Pompeius Magnus, legatus of Lucius Cornelius Sulla Felix against the Populares forces commanded by Gaius Marcius Censorinus who was in turn the legatus of Gnaeus Papirius Carbo. The battle resulted in a decisive Optimate victory. Immediately following the battle, the town was subjected to a brutal sacking by Sulla's victorious forces.
