The new genus and species Barsboldia sicinskii is here erected, based on an incomplete postcranial skeleton found in the Upper Cretaceous Nemegt Formation at the Nemegt locality, Gobi Desert, Mongolian People's Republic. It is the first lambeosaurine dinosaur so far described from this formation. The most striking character of B. sicinskii is the long club-like neural spines on the anterior caudals.

Key words: Dinosauria, Ornithischia, Hadrosauridae, Lambeosaurinae, anatomy, Upper Cretaceous, Mongolia.
