Daduhepa (also written Daduḫepa or Duduḫepa) was a Hittite queen (Tawananna) who reigned in the 14th century BC.
[1] In some sources, Daduhepa is stated to have been a wife of Šuppiluliuma I along with Ḫenti, who also had a Hurrian name.
[3] In more recent studies, evidence points to Daduhepa being the consort of Šuppiluliuma's father, who is known as Tudḫaliya or Tašmišarri.
[4] She has been found depicted and named on several seals alongside her son Šuppiluliuma.
She retained her status until her death around 1345 BC, after which Henti, the first wife of Šuppiluliuma, assumed the title of Tawananna and the queenship.
