Eoholocentrum ("dawn Holocentrum") is an extinct genus of prehistoric marine ray-finned fish that lived during the early Eocene.

It contains a single species, E. macrocephalum, known from the Early Eocene of Monte Bolca, Italy.

[4][5] It was originally erroneously named by Volta (1796) as a fossil specimen of "Holocentrus sogo" (a synonym for Holocentrus adscensionis) and then as a specimen of "Chaetodon saxatilis" (a synonym for Abudefduf saxatilis).

It was described as its own species in Holocentrus by de Blainville (1818)[6] before being placed in its own genus in 1975.
