Eryopidae were a group of medium to large amphibious temnospondyls,{{cite journal|author=R. R. Schoch|date=January 2013|title=The evolution of major temnospondyl clades: An inclusive phylogenetic analysis|journal=Journal of Systematic Palaeontology|volume=11|issue=6|doi=10.1080/14772019.2012.699006}} known from North America and Europe. They are defined as all eryopoids with interpterygoid vacuities (spaces in the interpterygoid bone) that are rounded at the front; and large external nares (Laurin and Steyer 2000). Not all of the genera previously included in the Eryopidae (Carroll 1988) are retained under the cladistic revisions.
