Acanthoclymeniidae is a family of early, primitive, clymeniid ammonoid cephalopods that lived during the Late Devonian.[1] At one time this family was known to contain a single genus, Acanthoclymenia, named by Hyatt in 1900, which is its type.

Acanthoclymeniidae are characterized by their small slightly involute, subdiscoidal, widely umbilicate shells that reach only a few centimeters in diameter. This description applies to the genus Acanthoclymenia as well.
