Ctenosauriscidae is an extinct family of pseudosuchian archosaurs within the clade Poposauroidea.

Ctenosauriscids are among some of the earliest archosaurs and represent the first global radiation of the group.

[2] Ctenosauriscidae was named by Oskar Kuhn in 1964 to include the genus Ctenosauriscus.

[3] It is a stem-based taxon defined by Richard J. Butler, Stephen L. Brusatte, Mike Reich, Sterling J. Nesbitt, Rainer R. Schoch and Jahn J. Hornung in 2011 as "the most inclusive clade containing Ctenosauriscus koeneni but not Poposaurus gracilis, Effigia okeeffeae, Postosuchus kirkpatricki, Crocodylus niloticus, Ornithosuchus longidens, or Aetosaurus ferratus".
