Cooperoceras is a genus of Tainoceratid nautiloid cephalopod molluscs within the superfamily Tainoceratoidea, characterized by and evolute shell with an open, perforate, umbilicus, sinuous ribs at maturity, and recurved hollow spines along the ventro-lateral shoulders. The flanks and venter are flattened, the flanks converge on the dorsum, the venter has a shallow median groove. The suture is with rounded ventral and lateral lobes. The siphuncle is small, tubular, and subcentral. (Kummel 1964, K413)

Cooperoceras, known from the Lower Permian of North America and Europe (Urals), was named by Miller in 1945. The genotype is Cooperoceras texanum.

Cooperoceras has also been found in rocks of Pennsylvanian age in Illinois.^[1]

The phylogenetic relationships of Cooperoceras are unclear.
