Rotaryus is an extinct genus of Early Permian trematopid dissorophoid temnospondyl known from the Free State of Thuringia of central Germany.

Rotaryus is known only from the holotype MNG 10182, articulated partial well-preserved skull and both mandibles and a closely associated partial postcranial skeleton. The postcranial skeleton includes several articulated neural arches with ribs, most of the left shoulder girdle, humeri, right radius and ulna, and a femur. It was collected from the uppermost part of the Tambach Formation, dating to the Artinskian stage of the Late Cisuralian Series (or alternatively upper Rotliegend), about 284-279.5 million years ago. It was found in the lowermost formational unit of the Upper Rotliegend Group or Series of the Bromacker Quarry, the middle part of the Thuringian Forest, near the village of Tambach-Dietharz. Rotaryus is only the second trematopid species to be reported from the Bromacker locality, and outside of United States, alongside Tambachia.
