Kef Governorate ( pronounced as /ar/; French: Gouvernorat du Kef) is one of the twenty-four governorates of Tunisia. It comprises chiefly part of the dorsal Atlas Mountains and their foothills in north-western Tunisia, bordering Algeria. It covers an area of 4,965 km2 and has a population of 243,156 (2014 census).[1] The capital is El Kef.
Twelve municipalities are in Kef Governorate:
Due to its close proximity to the Algerian border and its historical role in the Algerian War of Independence, Kef has a significant Algerian population, hosting over 6,000 registered Algerian voters, the second largest such community in Tunisia after Tunis.[2] Its capital city, El Kef, was the command centre of the Front de Libération Nationale during the Algerian War of Independence against the French in the 1950s.
