The Elamite War (c. 1765 BC - c. 1764 BC) was a war that was fought in the Middle East.

In order to consolidate its position, Elam tried to start a war between Babylon and Larsa. Babylon and Larsa made an alliance when they discovered this duplicity. Elam then began an invasion of Babylon. Around 1765 BC, Upi was captured by Elam after a siege. They then retreated for the rest of the year. Around 1764 BC, Yamhad sent an army of 10,000 troops to aid Babylon and Larsa, while Elam put the city of Hiritum under siege. They retreated after the city was relieved by a Mari army. Despite being allied to Babylon, Larsa remained neutral during the war.
