Tarchia (meaning "brainy one") is a genus of herbivorous ankylosaurid dinosaur from the late Cretaceous of Mongolia.

==Discovery and naming== thumb|left|Barun Goyot Formation in Mongolia In 1970, a Polish-Mongolian expedition discovered an ankylosaurian skull near Khulsan. In 1977, Teresa Maryańska named and described the type species Tarchia kielanae. The generic name is derived from Mongolian тархи (tarkhi, "brain") and Latin ~ia, in reference to a brain size presumed larger than that of the related form Saichania. The specific name honours Professor Zofia Kielan-Jaworowska, the leader of the expedition.
