The Battle of Dyrrhachium (near present-day Durrës in Albania) took place on October 18, 1081 between the Byzantine Empire, led by the Emperor Alexios I Komnenos (r. 1081–1118), and the Normans of southern Italy under Robert Guiscard, Duke of Apulia and Calabria. The battle was fought outside the city of Dyrrhachium (also known as Durazzo), the Byzantine capital of Illyria, and ended in a Norman victory.

Following the Norman conquest of Byzantine Italy and Saracen Sicily, the Byzantine emperor, Michael VII Doukas (r. 1071–1078), betrothed his son to Robert Guiscard's daughter. When Michael was deposed, Robert took this as an excuse to invade the Byzantine Empire in 1081. His army laid siege to Dyrrhachium, but his fleet was defeated by the Venetians. On October 18, the Normans engaged a Byzantine army under Alexios I Komnenos outside Dyrrhachium. The battle began with the Byzantine right wing routing the Norman left wing, which broke and fled. Varangian mercenaries joined in the pursuit of the fleeing Normans, but became separated from the main force and were massacred. Norman knights in the centre attacked the Byzantine centre and routed it, causing the bulk of the Byzantine army to rout.

After this victory, the Normans took Dyrrhachium in February 1082 and advanced inland, capturing most of Macedonia and Thessaly. Robert was then forced to leave Greece to deal with an attack on his ally, the Pope, by the Holy Roman Emperor, Henry IV (r. 1084–1105). Robert left his son Bohemond in charge of the army in Greece. Bohemond was initially successful, defeating Alexios in several battles, but was defeated by Alexios outside Larissa. Forced to retreat to Italy, Bohemond lost all the territory gained by the Normans in the campaign. The Byzantine recovery began the Komnenian restoration.
