The Kingdom of Tlemcen or Zayyanid Kingdom of Tlemcen (Arabic: ุงูุฒูุงูููู) was a kingdom ruled by the Berber Zayyanid dynasty in what is now the northwest of Algeria. Its territory stretched from Tlemcen to the Chelif bend and Algiers, and at its zenith reached Sijilmasa and the Moulouya River in the west, Tuat to the south and the Soummam in the east.
The Tlemcen Kingdom was established after the demise of the Almohad Caliphate in 1236, and later fell under Ottoman rule in 1554. The capital of the kingdom was Tlemcen, which lay on the primary eastโwest route between Morocco and Ifriqiya. The kingdom was situated between the realm of the Marinids to the west, centred on Fez, and the Hafsids to the east, centred on Tunis.
