Nanosiren garciae is an extinct sirenian mammal, a pygmy, tusked sea cow of the family Dugongidae, of the genus Nanosiren, living in warm shallow seas approximately 11.610 — 3.6 Ma during the Miocene, existing approximately 8.01 million years. It is evolutionarily related to modern species of manatees and dugongs.

Nanosiren garciae, an extinct sirenian, was classified and named in 2008 based on fossils uncovered from the Bone Valley Formation near Tampa, Florida. It is the smallest known post-Eocene sirenian, with body lengths of about 2 meters and weighing about 150 kg. Newborn nanosirens may have weighed only 6.8 kg. Its small size gave rise to the naming of its genus as Nanosiren, from the Greek for a “dwarf siren”. These mammals were of shallow draft and possessed small, conical tusks, suggesting they foraged in shallower waters than their dugong relatives. Nanosiren likely fed on smaller seagrasses near shorelines. They thrived approximately 5 million years ago during the Pliocene age.

The species was described and named by Daryl P. Domning of Howard University and Orangel A. Aguilera of the Universidad Nacional Experimental Francisco de Miranda, Venezuela in 2008. The name was chosen to commemorate famed Florida paleontologist Frank A. Garcia, who uncovered many fossil samples of the extinct mammal from the Bone Valley phosphate mines in Central Florida.
