Pimoidae is a small family of araneomorph spiders first described by Jörg Wunderlich in 1986. As re-circumscribed in 2021, it is monophyletic, and contained 86 species in two genera. It is closely related to the Linyphiidae, and is sometimes treated as synonymous with that family.

The species Pimoa cthulhu, described by Gustavo Hormiga in 1994, is named for Howard Phillips Lovecraft's mythological deity Cthulhu.
