Zhyraornis is a genus of prehistoric bird from the late Cretaceous period (middle Turonian, 92 mya). Its fossils have been found in Bissekty Formation deposits near Dzharakuduk in the Kyzyl Kum, Uzbekistan. Two species have been assigned to this genus: "Zhyraornis kashkarovi" and "Zhyraornis logunovi". Both are known only from partial pelvic bones ("synsacra").
