Eorpidae is a small family of extinct insects in the scorpionfly order, Mecoptera, which contains a single genus, Eorpa.

Three Eocene age species found in Western North America have been placed into the genus: E. elverumi, E. jurgeni, and E. ypsipeda.

The genus name is a combination of Eos, the Greek mythology goddess of dawn, a reference to the Eocene and "-orpa", a common suffix for mecopterans.

Similarly jurgeni is a patronym recognizing Jurgen Mathewes for years of collecting and research assistance at Quilchena.

The elongated abdomen as seen in Holcorpidae, and by the much less curved nature of "Radial1" vein seen in Dinopanorpidae separate Eorpidae from those two families.

[1] E. elverumi has a forewing that is light in color to largely hyaline, with a darker tone to the pterostigmal region.

[1] The hindwing of E. jurgeni is similar in outline to E. elverumi in that it is broad in depth, but unlike that species, it has a mottled color patterning to the wing.
