Naraoia is a genus of small to average size (about 2-4½ cm long) marine arthropods within the family Naraoiidae, that lived from the early Cambrian to the late Silurian period.

The name is derived from Narao, the name of a group of small lakes in Cataract Brook canyon, above Hector on the Canadian Pacific Railway, British Columbia, Canada.

At least the anterior trunk limbs have exopods with large, paddle-shaped distal lobes and short flattened side branches (setae) on the shaft.

[2] Species of Naraoia are known from Canada, the United States, South China, and Australia, occurring in deposits ranging from the Lower Cambrian (Atdabanian) to the late Upper Silurian (Pridoli).

[4] The large, paddle-shaped distal lobes and short lamellar setae on the exopods, the implanting of the antennas to the side, and the angle of the cephalon with the pygidium of up to 90° with which many specimen are found, all agree with a life of burrowing.
