The Catophragmidae are a family of barnacles in the superfamily Chthamaloidea with eight shell wall plates (rostrum, carina, paired rostrolatera, carinolatera I and carinolatera II), surrounded by several whorls of imbricating plates. The basis is membranous.[3]:57

This family occupies lower to upper midlittoral warm seas of the Pacific Coast of Central America, Caribbean, Bermuda, and Australia/Tasmania.[3]:57[4] These populations are highly disjunct and can be seen as relictual.

Two subfamilies are recognized:

The family contains these genera:[5] All genera are at present monotypic.

The Catophragmidae have historically suffered from a lack of systematic attention. Ross and Newman, 2001[4] published a revision of the family, proposing one new genus and creating two subfamilies. The family was discussed as representing very early balanomorph lineages. The known species conserve many plesiomorphic traits.
