Menaspiformes are an extinct order of holocephalans known from the Carboniferous and Permian periods,[1] with a possible member, Listracanthus,[2] known from the Early Triassic.

Members of the order are believed to be durophagous benthic carnivores.

[1][3] While historically menaspiforms were classified under Chimaeriformes,[2] they are today recognized as a separate order.
