Ornitomimosauria, ornitomimosaurus ("kadal mimik-burung") atau dinosaurus burung unta[7] adalah dinosaurus theropoda yang menyerupai burung unta modern. Dinosaurus ini merupakan dinosaurus omnivora atau herbivora yang dapat bergerak cepat. Dinosaurus ini hidup pada masa Kapur di Laurasia (kini Asia, Eropa dan Amerika Utara), Afrika dan kemungkinan Australia.[8] Kelompok ini pertama kali muncul pada masa Kapur Awal dan dapat bertahan hingga masa Kapur Akhir. Beberapa genus yang termasuk dalam kelompok ini adalah Nqwebasaurus, Pelecanimimus, Shenzhousaurus, Hexing dan Deinocheirus, dengan panjang lengan yang mencapai 2,4 m. Terdapat pula famili Ornithomimidae, dan di dalamnya terdapat genus Gallimimus, Struthiomimus dan Ornithomimus. Beberapa paleontolog (seperti Paul Sereno) menganggap Alvarezsauridae sebagai kerabat dekat ornitomimosaurus dan mengklasifikasikan keduanya ke dalam superfamili Ornithomimoidea.
