Gravigrada is the name of a suborder of Mammals established by the French naturalist Henri-Marie Ducrotay de Blainville in 1839, within the order Quaternates. He included three genera in the suborder: Elephas, Dinotherium and Manatus (Trichechus).

The name is no longer considered valid, as the animals that were included within Gravigrada are now believed to belong to two different orders, Sirenia and Proboscidea.
