The Galatheoidea are a superfamily of decapod crustaceans comprising the porcelain crabs and some squat lobsters. Squat lobsters within the three families of the superfamily Chirostyloidea are not closely related to the squat lobsters within the Galatheoidea. The fossil record of the superfamily extends back to the Middle Jurassic genus Palaeomunidopsis.
These families and genera are included:

Hu & Tao, 1996Pseudoporcellanella Sankarankutty, 1961Raphidopus Stimpson, 1858Ulloaia Glassell, 1938Two further fossil taxa may be included in the superfamily, but were not considered in the latest synopsis. The family Retrorsichelidae contains the single species, Retrorsichela laevis from the Campanian, which was tentatively placed in Galatheoidea by its authors. The Eocene genus Ovocarcinus, containing only O. elongatus, was originally placed incertae sedis.
