Puzur-Ashur I (Akkadian: 𒁍𒀫𒀸𒋩, romanized: Pu-AMAR-Aš-ŠUR) was an Assyrian king in the 21st and 20th centuries BC.
He is generally regarded as the founder of Assyria as an independent city-state, c. 2025 BC.
[3] Puzur-Ashur I may have started a native Assyrian dynasty that endured for eight generations until Erishum II was overthrown by the Amorite Shamshi-Adad I.
[citation needed] Hildegard Lewy, writing in the Cambridge Ancient History, rejects this interpretation and sees Puzur-Aššur I as part of a longer dynasty started by one of his predecessors, Sulili.
[2]: 14 Puzur-Ashur I's successors bore the title Išši’ak Aššur, vice regent of Assur, as well as ensí.
