Chionoecetes bairdi is a species of crab known alternatively as bairdi crab and tanner crab. C. bairdi is closely related to Chionoecetes opilio, and it can be difficult to distinguish C. opilio from C. bairdi. Both species are found in the Bering Sea and are sold commercially under the name "Snow crab". Tanner crabs have suffered from overfishing and as a result strict controls have been placed on tanner crab fisheries.
