'''嗜鳥龍'''（屬名：''Ornitholestes''）意為「搶劫鳥類者」，是種小型獸腳亞目恐龍，生存於晚侏儸紀的勞亞大陸西部，約為現在的北美洲。對於嗜鳥龍的瞭解幾乎都來自單一個化石，該化石在1900年發現於懷俄明州的科莫懸崖附近，並由亨利·費爾費爾德·奧斯本（Henry Fairfield Osborn）在1903年所敘述。後來發現一個手部化石，被歸類於嗜鳥龍，但這分類仍有所爭議。嗜鳥龍的種名''hermanni''是用來紀念美國自然歷史博物館的標本製作人員Adam Hermann。

嗜鳥龍是種虛骨龍類恐龍，有許多地方類似美頜龍，但體型稍大。似鳥龍的手部較長、較有效率、可以抓握。牠們擁有小型、銳利的牙齒，可能以小型獵物為食，例如蜥蜴與哺乳類。嗜鳥龍有時被重建時，口鼻部上會加上突起物，類似原角鼻龍；然而這論點最近已被卡彭特等人所反駁，他們指出這突起物其實是斷掉的鼻部骨頭。

在1940年的幻想曲》（Fantasia）的《春之祭》段落，一隻嗜鳥龍跳躍起捕抓一隻始祖鳥。

在BBC的電視節目《與恐龍共舞》（Walking with Dinosaurs）第二集，一隻嗜鳥龍正追蹤一隻幼年梁龍。

'''''Ornitholestes''''' ("bird robber") was a small theropod dinosaur of the late Jurassic of Western Laurasia (the area that was to become North America). To date, it is known only from a single partial skull and skeleton, found near Como Bluff, Wyoming, in 1900, and described by Henry Fairfield Osborn in 1903.<ref name=HFO03></ref> A hand was later attributed to ''Ornitholestes'', although it now appears to belong to ''Tanycolagreus''.<ref name=CMOC05></ref> The species name honors the AMNH preparator Adam Hermann.

''Ornitholestes'' was a coelurosaur, similar in many ways to ''Compsognathus'', though somewhat larger. It had small, sharp teeth and probably preyed on small animals such as lizards and mammals. ''Ornitholestes'' is sometimes illustrated with a crest on the snout (similar to that of ''Proceratosaurus''); however this has recently been disproved by Carpenter ''et al''., which indicated that the 'crest' was actually a broken nasal bone.<ref name=CMOC05/>

==Popular culture==
The animated film ''Fantasia'' included, in the Rite of Spring segment, what appears to be an ''Ornitholestes'' leaping at an ''Archaeopteryx''.

An ''Ornitholestes'' with a snout crest appeared in the second episode of ''Walking with Dinosaurs'' as a main enemy of ''Diplodocus'' youngsters.  It also appears in
''The Ballad of Big Al'' (a ''Walking with Dinosaurs'' special) where it tries to eat newborn ''Allosaurus''.
