The common logperch (Percina caprodes), sometimes simply known as the logperch, is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. Like other logperches, it has the typical vertical barring along the flank and a subterminal mouth.

This is the most widespread logperch, commonly found in large parts of the eastern United States and Canada. Like other logperches, they inhabit clear, gravelly streams and lakes, reaching a maximum size of about 18 centimeters (7.1 in) and a maximum age of about 3 years. They play a key role in the reproduction of the snuffbox mussel (Epioblasma triquetra).
