The wreckfish are a small group of ray-finned fish in the genus Polyprion, belonging to the monotypic family Polyprionidae in the order Acropomatiformes.

Atlantic wreckfish (Polyprion americanus) are a long-lived commercial species in the Mediterranean, the south-eastern Pacific and the Atlantic Ocean.

The genera Lateolabrax and Stereolepis have previously been classified in Polyprionidae, but they are currently placed in their own monogeneric families Lateolabracidae and Stereolepididae.
