Ibbi-Sipish (ca. 23rd century BC) was the fifth king of Ebla. He was the son of the most powerful king of Ebla, Ibrium, and the first to succeed in a dynastic line, breaking with the tradition of an elected 7 year rule.
Ibbi-Sipish visited cities, such as Kish, abroad. He also concluded a treaty with Armi (Aleppo). During his rule there was an internal revolt, possibly against the new concept of absolute and dynastic kingship. This led to the eventual weakening of the city. It is now thought that Sargon or perhaps his grandson Naram-Sin destroyed the city.
