Diparidae is a family of chalcid wasps. This group was formerly treated as Diparinae, a subfamily of Pteromalidae.

Most diparids are collected from leaf litter in forests, where they are known to parasitise weevils, although diparids have been known to emerge from mantid egg cases and fly pupae. They are found almost worldwide, but appear to have Gondwanan roots, with most diversity (at genus level) in South Africa and Australia.
