Elasenia is a genus of Ediacaran animals. The genus contains two species.^[1]^[2]^[3]

The genus was formerly included under Inordozoa , incertae sedis by Fedonkin. It was classified as a Coelenterate, but after the break up of the taxon into two different phylums - Cnidaria and Ctenophora - the current position of this animal is uncertain.^[4] It may be related to the extinct Trilobozoans (now considered a separate phylum) or the possible cnidarian class Cyclozoa.
