Chenoprosopus is an extinct genus of temnospondyl amphibian. Chenoprosopus resembles the European genus, Archegosaurus. Of the Permian amphibia found in the United States, Chenoprosopus most resembles Cacops though it differs in the smaller nostrils and in their posterior position.

 In 1911, Mr Paul Miller discovered in New Mexico part of the skull of a new species of Chenoprosopus and gave it the name Chenoprosopus milleri. The skull was long and narrow, 28 cm (11.0 in) long and 5.4 cm (2.1 in) wide. The teeth were stout and conical, slightly recurved and about 19 mm (0.7 in) long. A single vertebra was also found at the site and this resembled the vertebrae of Diadectes.
