Tripoli Eyalet is an eyalet of the Ottoman Empire.

The capital is in Tripoli. Its reported area in the nineteenth century is 1,629 square miles (4,220 km2).

It extends along the coast, from the southern limits of the Amanus mountains in the north, to the gorge of al-Muamalatayn to the south, which separates it from the territory of the sanjak of Sidon-Beirut.

Along with the chiefly Sunni Muslim coastal towns of Latakia, Jableh, Baniyas, Tartus, Tripoli, Batrun and Byblos, the eyalet includes the An-Nusayriyah Mountains, inhabited by Alawites, as well as the northern reaches of the Lebanon range, where the majority of inhabitants are Maronite Christians.
