Palaeoniscum (from , 'ancient' and 'cod-fish' or 'woodlouse') is an extinct genus of ray-finned fish from the Middle to Late Permian period (Guadalupian-Lopingian) of England, Germany, Turkey, North America and Greenland, and possibly other regions. The genus was named Palaeoniscum in 1818 by Henri Marie Ducrotay de Blainville, but was later misspelled as Palaeoniscus by Blainville and other authors (notably Louis Agassiz). Palaeoniscum belongs to the family Palaeoniscidae.

P. freieslebeni is the most common taxon in the Wuchiapingian aged Kupferschiefer and Marl Slate, where it constitutes 80% of all fish fossils. The genus is considered to be a poorly defined wastebasket taxon.
