The siege of Berat took place in July 1455 when the Albanian army of Skanderbeg attempted to capture the fortress in the Albanian city of Berat, which was held by Ottoman forces. The attempt resulted in a failure when an Ottoman relief army arrived and routed the besieging forces.

Gjergj Kastrioti, commonly known as Skanderbeg, was an Albanian feudal lord and military commander who led a rebellion against the Ottoman Empire in what is today Albania, North Macedonia, Greece, Kosovo, Montenegro, and Serbia.
