Beiguornis is a genus of bohaiornithid bird from the Early Cretaceous Longjiang Formation of Inner Mongolia, China. The genus contains a single species, Beiguornis khinganensis. Beiguornis is the first and only enantiornithine bird known from the Longjiang Formation. In the phylogenetic analysis conducted by the describing authors, Beiguornis formed a monophyletic group with the bohaiornithids Sulcavis and Zhouornis.[2]
