Stegomastodon ('roof breast tooth') is an extinct genus of gomphothere, a family of proboscideans. It is not to be confused with the genus Mammut from a different proboscidean family, whose members are commonly called "mastodons", nor with the genus Stegodon, from yet another proboscidean subfamily, whose members are commonly called "stegodonts". The Stegomastodon was one of the smaller species through the genus. It ranged through North and possibly South America.
