驰龙科（Dromaeosauridae）又译奔龙科，是群类似鸟类的兽脚亚目恐龙。牠们是群体型中至小型的肉食性恐龙，繁盛于白垩纪。在非正式的用法里，牠们通常被称为「盗龙」（Raptor），这个名称因为电影《侏㑩纪公园》（Jurassic Park）出现的伶盗龙而开始盛行。驰龙科的属名在希腊文意为「奔跑的蜥蜴」，dromeus / δρομευς 意为「奔跑」，而sauros / σαυρος 意为「蜥蜴」。

驰龙科的恐龙分布范围可能极广，化石在北美洲、欧洲、非洲、亚洲、南美洲以及南极洲等地都有发现记录。已知最原始的驰龙类恐龙记录来自在英格兰西南部被发现的牙齿化石，推测生活于侏㑩纪巴通阶，而后来演化并且持续存活到白垩纪末的马斯垂克阶，据此推算，驰龙类出现在地球上的时间超过1亿年。

Dromaeosauridae is a family of feathered theropod dinosaurs. They were small- to medium-sized feathered carnivores that flourished in the Cretaceous Period. The name Dromaeosauridae means 'running lizards', from Greek dromeus (δρομευς) meaning 'runner' and sauros (σαυρος) meaning 'lizard'. In informal usage they are often called raptors (after Velociraptor), a term popularized by the film Jurassic Park; a few types include the term "raptor" directly in their name and have come to emphasize their supposed bird-like habits.
