The Zayyanid dynasty is a Berber Zenata dynasty that rules the Kingdom of Tlemcen, an area of northwestern Algeria, centered on Tlemcen.

The territory stretches from Tlemcen to the Chelif bend and Algiers, and at its zenith reaches the Moulouya river to the west, Sijilmasa to the south and the Soummam river to the east.

Their rule lasts from 1235 to 1556.
