Coliath (Arabic: قلعة قليعات Qalaat al-Qlaiaat; French: Colée) are ruins of a fortification of the crusaders in Lebanon.

It was then reoccupied by the Franks, but it was the Mamluk sultan Baibars who, in the summer of 1266, completely ruined it as a prelude to the capture of Tripoli.

Its defensive role was mediocre, so it was generally used as a dwelling for a troop in the field in times of war, as a base for economic domination in times of peace, or more simply as a place of refuge against raiders.

The plan of its construction is that of a castrum (enclosure castle) similar to that of several other sites fortified by military orders in the region.

It is a square enclosure flanked by towers, housing on its reverse side large vaulted multifunctional halls.
