'''''Beckius''''' is an extinct genus of marine whitefish known from the Early Oligocene<ref>{{Cite journal |last=E. R. Atwill (2) |date=1935 |title=Oligocene Tumey Formation of California |url=http://search.datapages.com/data/doi/10.1306/3D932D52-16B1-11D7-8645000102C1865D |journal=AAPG Bulletin |language=en |volume=19 |doi=10.1306/3D932D52-16B1-11D7-8645000102C1865D |issn=0149-1423|url-access=subscription }}</ref> of California. It contains a single species, '''''B. plicatus''''', known only from a single fossilized scale from the Tumey Formation, a lens of the Kreyenhagen Shale. The scale was found to resemble those of ''Coregonus'', although significantly different in many ways, leading to its classification as a new genus of Coregoninae.<ref>{{Cite web |title=PBDB Taxon |url=https://paleobiodb.org/classic/checkTaxonInfo?taxon_no=364701&is_real_user=1 |access-date=2024-04-19 |website=paleobiodb.org}}</ref><ref>{{Cite journal |last=David |first=Lorre R. |date=1946 |title=Some Typical Upper Eogene Fish Scales from California |url=https://authors.library.caltech.edu/records/v03cm-86s21 |journal=Contributions to Paleontology |volume=IV}}</ref><ref>{{Cite web |title=Mineralienatlas - Fossilienatlas |url=https://www.mineralienatlas.de/lexikon/index.php/FossilData?lang=de&fossil=Beckius |access-date=2024-04-19 |website=www.mineralienatlas.de |language=de}}</ref>
The genus name was later reused in 1992 for a scarab beetle from New Guinea, until it was discovered to be preoccupied; the beetle was thus renamed ''Debeckius''.<ref>{{Cite journal |last=Allsopp |first=Peter G |date=2022-07-01 |title=Replacement names for ''Beckius'' Dechambre, 1992 and Syrictes Prell, 1936, and validation of ''Neoryctes'' Arrow, 1908 (Coleoptera: Scarabaeidae: Dynastinae) |journal=Zootaxa |volume=5165 |issue=2 |pages=294–300 |doi=10.11646/zootaxa.5165.2.9 |issn=1175-5334 |pmid=36095466}}</ref>
