Ljubuški is a town and municipality in Bosnia and Herzegovina. It is located in the West Herzegovina Canton, a unit of the Federation of Bosnia and Herzegovina.

The Ljubuški Old Town is located at a prominent rocky top of the mountain chain Buturović.

The whole complex of the Old Town Ljubuški is an irregular polygon, with a total area of 3350 square meters. The Old Fortress of Ljubuški, which is build around 1444, dominates the town and the Trebižat River valley. Duke Stjepan Vukčić Kosača and his sons Vladislav Vukčić Kosača and Vlatko Vukčić Kosača challenged each other in 1452 to obtain it. They were blood family stories. Over the Muslim years, the fort became a frontier outpost of the Ottoman Empire; then it was abandoned in 1835 because it lost its importance. The Ljubuški Old Town is declared to be a national cultural monument of the country in 2003.
