Shengjingornis is a genus of enantiornithean bird known from the Early Cretaceous of Jinzhou, western Liaoning, China. Its remains were discovered in Jiufotang Formation deposits, dated to 120 million years ago.^[1]

Shengjingornis is considerably larger when compared to other longipterygids; combined with its poorly-preserved skull and bizarre claw and digit anatomy similar to both those of birds of prey and ground birds, its lifestyle is unclear.^[2]
