Bagaraatan (meaning "small hunter" in Mongolian) is an extinct genus of theropod dinosaur from the Late Cretaceous period. Its fossils were found in the Nemegt Formation of Mongolia. Bagaraatan may have been around 3-4 meters in length. The type species, B. ostromi, was described by Osmolska in 1996. The post-cranial (ZPAL MgD-I/108) skeleton has been described as "bird-like", while the skull exhibits features of several different theropod groups. Holtz classified it as a basal tyrannosauroid, Coria identified it as a troodontid, and Rauhut placed it in maniraptora.
