Cephaloxenus is an extinct genus of prehistoric marine ray-finned fish that lived during the early Ladinian stage of the Middle Triassic epoch.

It contains two species:

• †C. macropterus Brough, 1939 - Ladinian of Italy and Switzerland
• †C. squamiserratus Bürgin, 1992 - Ladinian of Italy

It was often classified as a peltopleurid, but has more recently been classified as a perleidiform in its own monotypic family, Cephaloxenidae.
