Purranisaurus is an extinct genus of marine crocodyliform from the Middle to Late Jurassic period of Chile and Argentina. Rusconi originally regarded Purranisaurus potens (the type species) to be a plesiosaur; however, Gasparini demonstrated that it was in fact a metriorhynchid crocodyliform, and that may be a junior synonym of Metriorhynchus.

 Recent phylogenetic analysis has shown that Purranisaurus is a distinct metriorhynchid genus. A subsequent study expanded the genus Purranisaurus to include Metriorhynchus casamiquelai and M. westermanni.
