Bagaraatan (/'ba-ɣa-raa-tan/ meaning 'small' baɣa + 'carnivorous animal, beast of prey' araatan in Mongolian) is a 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 to 4 metres (9.8 to 13 ft) in length.
The type species, B. ostromi, was described by Osmolska in 1996. The post-cranial ( MgD-I/108) skeleton has been described as "bird-like", while the skull exhibits features of several different theropod groups.

Holtz classified Bagaraatan as a basal tyrannosauroid, Coria identified it as a troodontid, and Rauhut placed it in Maniraptora.[1] et al. placed it in basal Tyrannosauroidea, agreeing with the placement by Holtz.[2]
Below is the cladogram by Loewen et al. in 2013.[2]
