Rhinophorinae is a subfamily of flies (Diptera), commonly known as Woodlouse Flies, found in all zoogeographic regions except Oceania, but mainly in the Palaearctic and Afrotropical regions.

They are small, slender, black, bristly flies phylogenetically close to the Tachinidae, formally many authors considered them a family, they are now a subfamily in the Calliphoridae. The larvae are mostly parasitoids of woodlice, beetles, spiders, and other arthropods, and occasionally snails.

By 2020, about 33 genera were placed in the family, with a total 177 species.
