Phillipsiidae is a family of proetid trilobites, the various genera of which comprise some of the very last of the trilobites, with a range that extended from the Kinderhookian epoch of the Lower Mississippian, to the Guadalupian epoch of the Upper Permian.

Phillipsiidae is sometimes defined as a subfamily, "Phillipsiinae," and usually placed within the family Proetidae. Jell & Adrain (2003) went so far as to lump Phillipsiidae into the family Proetidae, however other workers since like Lerosey-Aubril and Feist (2005) have continued to recognize Phillipsiidae as a distinct and separate family within Proetida.
