Haplomastodon is an extinct genus of proboscidea endemic to South America during the Pleistocene from 1.810 Ma—11,000 years ago, living for approximately 1.789 million years.[1]

It had two tusks on either side of a trunk like other members of Gomphotheriidae. Its apparent range was from Venezuela southward to Argentina where fossils were recovered in the Suelo Formation, a quarry dig in Corrientes Province.[2] It may have shared its habit with Notiomastodon based on genus age and geography.
