Kotor (Montenegrin Cyrillic: Котор, pronounced [kɔ̌tɔr]) is a coastal town in Montenegro. It is located in a secluded part of the Gulf of Kotor. The city has a population of 13,510 and is the administrative center of Kotor Municipality.

The old Mediterranean port of Kotor is surrounded by fortifications built during the Venetian period. It is located on the Bay of Kotor (Boka Kotorska), one of the most indented parts of the Adriatic Sea. Some have called it the southern-most fjord in Europe, but it is a ria, a submerged river canyon. Together with the nearly overhanging limestone cliffs of Orjen and Lovćen, Kotor and its surrounding area form an impressive and picturesque Mediterranean landscape.
