Beckius is an extinct genus of marine whitefish known from the Early Oligocene[1] 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.[2][3][4]

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.[5]
