The Jarrahids (also known as Banu al-Jarrah) were an Arab dynasty that intermittently ruled Palestine and controlled Transjordan and northern Arabia in the late 10th and early 11th centuries. They were described by historian Marius Canard as a significant player in the Byzantine–Fatimid wars in Syria who "created for themselves, in their own best interests, a rule of duplicity, treason and pillage". They were the ruling family of the Tayy tribe, one of the three powerful tribes of Syria at the time; the other two were Kalb and Kilab.
