Abba-El I (reigned c. 1750 BC – c. 1720 BC - Middle chronology) was the fourth great king of Yamhad (Halab), succeeding his father Hammurabi I.^[1]

Hammurabi I left Yamhad a prosperous country, and Abba-El's reign was relatively peaceful. He maintained good commercial relations with Babylon.^[2] The main event of his reign was the rebellion of Zitraddu, governor of the city Irridu which belonged along with its district to Abba-El's brother Yarim-Lim

A tablet discovered at Alalakh explains the circumstances which led to the forming of the kingdom of Alalakh; it revealed that Abba-El destroyed Irridu and compensated his brother by giving him Alalakh as a hereditary kingdom for his dynasty under the suzerainty of Aleppo but that it should be forfeited if Yarim-Lim or his descendants committed treason against Yamhad.

Abba-El took an oath upon himself not to confiscate his brother's new kingdom and that he might be cursed if he ever did.^[3] In return Yarim-Lim took an oath of loyalty to his brother, specifying that if he or his descendants ever committed treason or spilled Abba-El's secrets to another king, their lands would be forfeited.^[4]

The Hurrians's influence seems clear during Abba-El's reign, as he recalls the help given to him by the Hurrian Goddess Hebat.^[5]

Abba-El died in ca. 1720 BC and was succeeded by Yarim-Lim II, who most probably was his son; however, Moshe Weinfeld believes that Yarim-Lim II was the same as Yarim-Lim of Alalakh.^[6]
