迅猛鳄科（Prestosuchidae）是群三叠纪肉食性主龙类。牠们是大型、活耀的陆地顶级掠食动物，身长2.5到7公尺。在那个时代，迅猛鳄科继承引鳄科在大型主龙类的地位。牠们与引鳄科的体型相似，在头颅与骨骼上的某些特征也有相似点，迅猛鳄科较先进的地方在于牠们的直立四肢、类似鳄鱼的足踝，显示更有效率的行走方式。迅猛鳄科繁盛于中三叠纪，以及晚三叠纪早期，化石已在欧洲、印度、坦噶尼喀、阿根廷、巴西等地发现。然而专家们对于这些物种的种系发生学关系，以及哪些属该被列入，迅猛鳄科是否与劳氏鳄科有所区别等议题上仍有歧见。

Prestosuchids were a group of Triassic carnivorous archosaurs. They were large active terrestrial apex predators, ranging from around 2.5 to 7 metres (8.2 to 23.0 ft) in length. They succeeded the Erythrosuchidae as the largest archosaurs of their time. While resembling erythrosuchids in size and some features of the skull and skeleton, they were more advanced in their erect posture and crocodile-like ankle, indicating more efficient gait. Prestosuchids flourished throughout the whole of the middle, and the early part of the late Triassic, and fossils are so far known from Europe, India, Africa (Tanganyika), Argentina,and Paleorrota in Brazil. However, experts disagree regarding the phylogenetic relationships of the group, what genera should be included, and whether indeed the Prestosuchidae constitute a distinct family apart from the Rauisuchidae.
