Sternotherus is a genus of aquatic turtles known commonly as musk turtles. It is closely related to the genus Kinosternon. The most common species in most of North America is Sternotherus odoratus, the commmon musk turtle or stinkpot; that entry has more information on the ecology of this group of turtles.

The genus occurs in southern Canada, as well as the United States and Mexico.

They are very similar to the American mud turtles, but tend to have a more domed carapace, with a distinctive keel down the center of it. Sternotherus odoratus typically grows to only 8–14 cm (3–5½ inches) in carapace length at full maturity, with females often being larger than males.

All musk turtles are carnivorous, consuming various aguatic invertebrates, fish, and carrion.

They are a highly aquatic genus. But some, like the Common Musk Turtle, are known to bask on fallen trees and coarse woody debris on shorelines.
