Erketu (meaning "Erketü Tengri") is a genus of somphospondylan dinosaur that lived in Asia during the Late Cretaceous roughly between 96 million and 89 million years ago. It is known from the Bayan Shireh Formation of Mongolia and its fossils were between 2002 and 2003 during field expeditions. Erketu was first described in 2006 and later on in 2010 due to some cervicals that were left behind in the expedition. Erketu represents one of the first sauropods described from the Bayan Shireh Formation. The elongated cervical vertebrae of Erketu indicates that it was the sauropod with the longest neck relative to its body size.
