Neognathae inggih punika infrakelas kedis, sane matungkalikan sareng ratites utawi Palaeognathae (unta, ému, kasuari, tinamou, kiwi, miwah sane lianan).

Sane mangkin, sawatara 10.000 spesies kedis saking infrakelas Neognathae maurip ring Gumi. Fosil sane pinih riin saking kedis-neognathae mawit saking yusa sawatara 90 yuta warsa (Kapur Akhir). Neognathae madué metakarpal sané masikian, digit kaping tiga sané memanjang, miwah 13 utawi kirang tulang belakang. Ipun mabinayan sareng palaeognathae ring fitur-fitur sekadi struktur tulang rahang.
