Eomyctophum ("dawn Myctophum") is an extinct genus of lanternfish that inhabited the Peri-Tethys region and later the Paratethys Sea from the Eocene to the Oligocene.[1] Its remains are known from throughout eastern Europe & western Asia in both the Caucasus and Carpathians. Fossils of this genus comprises both articulated skeletons and otoliths suggesting it was a particularly common genus of fish.[2][3]

It is the only member of the extinct subfamily Eomyctophinae, although Eokrefftia may also belong in it.[4] The earliest known member of the genus was identified from the Early Eocene of Italy in 2025, millions of years earlier and further west than the other species.[5]
