Washukanni (also spelled Waššukanni) was the capital of the Hurrian kingdom of Mitanni, from around 1500 BC to the 13th century BC. Its precise location is unknown. A proposal locates it under the largely unexcavated mound of Tell el Fakhariya, near Tell Halaf in Syria, but this idea was rejected by Edward Lipinski. However, this identification received a new support by Stefano de Martino, Mirko Novák and Dominik Bonatz due to recent archaeological excavations by a German team.
The city is known to have been sacked by the Hittites under Suppiluliuma I (reigned c. 1344–1322 BC) in the first years of his reign, whose treaty inscription relates that he installed a Hurrian vassal king, Shattiwaza. The city was sacked again by the Assyrian king Adad-nirari I around 1290 BC, but very little else is known of its history.
