Bohaiornithidae is a group of early enantiornithine birds from the early Cretaceous Period of China. All known specimens come from the Jiufotang Formation and Yixian Formation, dating to the early Aptian age, 125-120 million years ago.^[1]

Bohaiornithidae was first coined as a family of enantiornithean birds by Wang and colleagues in 2014. They defined it as the natural group formed by all descendants of the common ancestor of the type species, Bohaiornis guoi, and Shenqiornis mengi.^[1]

The cladogram below was found in the phylogenetic analysis of Wang et al. 2014, which itself was an updated version of O’Connor et al. 2013.^[2] The cladogram is based on a data matrix that includes 56 avialaen taxa, scored based on 262 morphological traits.^[1]
