Stylopidae is a family in the order Strepsiptera. There are about 15 genera and more than 330 described species in Stylopidae.

All Strepsiptera, including all members of Stylopidae are parasitic insects. Host insects of this family that are afflicted are referred to as being "stylopized".

Stylopidae (not to be confused with the clade Stylopidia) are strictly parasites of bees. However, other strepsipteran families such as Corioxenidae, Elenchidae, Halictophagidae, Myrmecolacidae, and Xenidae are known to use members of Blattodea, Mantodea, Orthoptera, Hemiptera, Diptera, and other Hymenoptera as hosts. Stylopized hosts sometimes display a variety of physical and behavioral changes.
