The Battle of Dyrrachium (or Dyrrhachium) took place from April to late July 48 BC near the city of Dyrrachium, modern day Durrës in what is now Albania. It was fought between Gaius Julius Caesar and an army led by Gnaeus Pompey during Caesar's civil war.

Caesar attempted to capture the vital Pompeian logistics hub of Dyrrachium but was unsuccessful after Pompey occupied it and the surrounding heights. In response, Caesar besieged Pompey's camp and constructed a circumvallation thereof, until, after months of skirmishes, Pompey was able to break through Caesar's fortified lines, forcing Caesar to make a strategic retreat into Thessaly.

After the battle, Pompey pursued Caesar into Thessaly and then towards Pharsalus, where the decisive battle of Caesar's Greek campaign would be fought.
