Qalaat Tannour is a Shepherd Neolithic archaeological site located halfway between Britel and Haour Taala, southwest of Baalbek in the Baalbek District of the Baalbek-Hermel Governorate in Lebanon.
The surface site was discovered by M. Besançon in 1966 on a hill of exposed limestone rocks. It was the furthest south of all of the Shepherd Neolithic sites catalogued at the time. Flint tools found at the location were generally in a brown or grey, some showing a white patina. Blade types were typically short but also included thin and backed varieties, steep-scrapers and cores. The material was stored with the Saint Joseph University, Museum of Lebanese Prehistory.
Several Roman tombs were also noted at the site.
