Eldredgeops rana (formerly Phacops rana) is a species of trilobite from the middle Devonian period. Their fossils are found chiefly in the northeastern United States, and southwestern Ontario.

Because of its abundance and popularity with collectors, Eldredgeops rana was designated the Pennsylvania state fossil by the state's General Assembly on December 5, 1988.[2]
