Boreopteridae (meaning "northern wings") is a group of ornithocheiromorph pterosaurs from the Aptian-age Lower Cretaceous Yixian Formation of Liaoning, China.In 2006, Lü Junchang and colleagues named the clade Boreopteridae for the clade containing the common ancestor of "Boreopterus" and "Feilongus" and all its descendants, which the authors reclassified as close relatives of the ornithocherids.
