The Kisrawan or Keserwan is a region between Mount Lebanon and the Mediterranean coast, north of the Lebanese capital Beirut and south of the Ibrahim River. It is administered by the eponymous Keserwan District, part of the Keserwan-Jbeil Governorate.

In the 12th–13th centuries it was a borderland between the Crusader states along the coast and the Muslim governments in Damascus. Its inhabitants at that time were Twelver Shia Muslims, Alawites, Druze and Maronite Christians. While the Kisrawanis acted independent of any outside authority, they often cooperated with the Crusader lords of Tripoli and Byblos. Soon after the Sunni Muslim Mamluks conquered the Crusader realms, they launched a series of punitive expeditions in 1292–1305 against the mountaineers of the Kisrawan. The assaults caused wide scale destruction and displacement, with Maronites from northern Mount Lebanon gradually migrating to the depopulated villages of the Kisrawan.
