'''''Cryptachaea''''' is a genus of spiders in the Theridiidae (tangle web spider) family.<ref name="World Spider Catalog"/>

==Taxonomy== Many species in this genus used to reside in ''Achaearanea'',<ref name="World Spider Catalog"/> which received a major revision in 2008 by Hajime Yoshida.<ref name=yoshida/> The genus was originally established as a subgenus of ''Theridion''.<ref name="World Spider Catalog"/><ref name=yoshida/>

==Distribution== This is mostly a New World genus, with many species in South America. One species is cosmopolitan, one species occurs in the whole Palearctic, another only in China.<ref name="World Spider Catalog"/> ''C. veruculata'' was introduced to Europe from New Zealand.

==Name== The genus name is a combination of ''Achaea'', the old name of the genus ''Achaearanea'', and Ancient Greek κρυπτός "hidden". The genus is called ''Iwama-himegumo zoku'' in Japanese.<ref name=yoshida/>
