Adad-Nirari or Hñaddu-Nirari was a king of Qatna in the 14th century BC.
Adad-Nirari is an Akkadian name. The king reigned for 45 years in the 14th century BC, and was mentioned in the inventories of Ninegal, found in Qatna. A tablet from Qatna records him stationing an army of chariot archers in the city of Tukad, in Mount Lebanon. The name of his queen was Pizallum.
Michael Astour suggested identifying Adad-Nirari with Adad-Nirari of Nuhaà ¡à ¡e; a hypothesis supported by Thomas Richter, who believes that Adad-Nirari ruled Qatna through a à ¡akkanakku (military governor) called Lullu, citing that the latter's name appears in the Qatanite inventories at the time of Adad-Nirari. According to Richter, Adad-Nirari of Nuhaà ¡à ¡e ruled the second Syrian power after Mitanni, and was removed by the Hittites which gave Qatna its independence back .
This theory is debated; the Shattiwaza treaty between Mitanni and the Hittites mentioned Qatna independently from Nuhaà ¡à ¡e during the Hittite king à  uppiluliuma I's first Syrian war; If Qatna was part of the Nuhaà ¡à ¡ite kingdom, its submission to the Hittites would not have been mentioned separately. Jacques Freu rejected Richter's hypothesis; citing different arguments, he concluded that Adad-Nirari of Nuhaà ¡à ¡e was a contemporary of Idadnda of Qatna who ruled during the first Syrian war, a successor of the Qatanite Adad-Nirari.
