Podocnemis is a genus of aquatic turtles, commonly known as South American river turtles, in the family Podocnemididae. The genus consists of six extant species occurring in tropical South America. Four additional species are known only from fossils. These turtles have pig-like noses but are not closely related to the pig-nosed turtle.
