Gomphotheres are any members of the diverse, extinct taxonomic family Gomphotheriidae. Gomphotheres were elephant-like proboscideans, but not belonging to the family Elephantidae. They were widespread in North America during the Miocene and Pliocene epochs, 12–1.6 million years ago. Some lived in parts of Eurasia, Beringia, and following the Great American Interchange into South America. Beginning about 5 million years ago, they were gradually replaced by modern elephants, apart from the last two South American genera, of which Cuvieronius did not become extinct until 9,100 BP, and Haplomastodon, by some authors reclassified into Notiomastodon, fossils have been dated to as recently as 6,060 BP in the Valle del Magdalena, Colombia. These gomphotheres also survived in Mexico and Central America until the end of the .
The name "gomphothere" comes from Ancient Greek γόμφος, "peg, pin; wedge; joint" plus θηρίον, "beast".
Gomphotheres differed from elephants in their tooth structure, particularly the chewing surfaces on the molar teeth. The earlier species had four tusks, and their retracted facial and nasal bones prompted paleontologists to believe that gomphotheres had elephant-like trunks.
Both the genus Gomphotherium and family Gomphotheriidae were erected by the German zoologist Karl Hermann Konrad Burmeister (1807-1892) in 1837.
