''Beckius'' is an extinct genus of marine
whitefish known from the
Early Oligocene 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 Kreyenhagen Shale is a geologic formation in California. It preserves fossils dating back to the Paleogene period.

. 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.
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''.
