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 (1888-1982) 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.
