Ductor (Latin for "leader", referencing its resemblance and potential relation to the pilotfish, Naucrates ductor) is an extinct genus of prehistoric marine ray-finned fish that lived during the early Eocene. It contains a single species, D. vestenae, known from the famous Monte Bolca site of Italy. It is the only member of the family Ductoridae. It is the earliest representative of the suborder Echeneoidei, and is thought to be most closely related to cobias and dolphinfish.
