Megalopidae is an ancient family of ray-finned fish, one of two living members of the order Elopiformes. It contains a single living genus (Megalops, the tarpons) with two species, and several extinct genera dating back to the Early Cretaceous. They likely diverged from their closest relatives, the Elopidae, during the Late Jurassic.
