Hamititan (meaning "Hami giant") is a genus of titanosaur sauropod dinosaur from the Shengjinkou Formation of Xinjiang, China.

[2] In 2006, a Konservat-Lagerstätte was reported from the Shengjinkou Formation in the Hami region of Xinjiang, China.

[2] The phylogenetic analysis of Wang et al. places Hamititan as a derived non-lithostrotian titanosaur in a polytomy with Epachthosaurus, Kaijutitan, Notocolossus, rinconsaurs, lognkosaurs, and lithostrotians.

A cladogram depicting the former hypothesis is shown below:[2] Andesaurus Wintonotitan Malarguesaurus Epachthosaurus Hamititan Kaijutitan Notocolossus Rinconsauria Lognkosauria Dreadnoughtus Lithostrotia Other animals from the holotype locality include the pterosaur Hamipterus and contemporary euhelopodid Silutitan, which is described in the same paper.

Together, Hamititan, the aforementioned fauna and an unnamed theropod represent the known vertebrate taxa of the area.
