Metriorhynchinae is a subfamily of metriorhynchid crocodyliforms from the late Middle Jurassic to the Early Cretaceous of Europe, North America and South America. Named by Fitzinger, in 1843, it contains the metriorhynchids Maledictosuchus, Gracilineustes, Metriorhynchus, Cricosaurus and Rhacheosaurus. The last three taxa form a tribe within Metriorhynchinae, the Rhacheosaurini. Metriorhynchinae is one of two subfamilies of Metriorhynchidae, the other being Geosaurinae.

Metriorhynchidae is an extinct family of specialized, aquatic metriorhynchoid crocodyliforms from the Middle Jurassic to the Early Cretaceous period of Europe, North America and South America. The name Metriorhynchidae was coined by the Austrian zoologist Leopold Fitzinger in 1843. The group contains two subfamilies, the Metriorhynchinae and the Geosaurinae. They represent the most marine adapted of all archosaurs.
