Exellia is a genus of extinct spadefish that lived in the Tethys Ocean during the early Paleogene.

The adult form is shaped akin to a large spadefish or a short dolphinfish, with very large pelvic fins, and a long dorsal fin starting from in front of the eyes to near the base of the caudal peduncle.

The earlier species, E. proxima, is known from the Danata Formation Lagerstätten from the Late Paleocene of Turkmenistan.

The latter-occurring species, E. velifer, is the better studied species, and is known from numerous adult and juvenile specimens from the Middle Eocene Monte Bolca Lagerstätten.

regard Exellia as a spadefish, though, some remove this genus, and the related Eoluvarus[1] to a separate family, "Exelliidae."
