Filistriatus is a genus of marine ray-finned fish from the family Polynemidae, the threadfins. Members of the genus are found across the Indo-Pacific, from the coast of East Africa to Hawaii. They were previously included in the genus Polydactylus, but were moved to a separate genus by Girard and Chovanec in 2025, because Polydactylus is otherwise non-monophyletic.
