Postredectes (meaning "last ichthyodectid") is an extinct genus of ichthyodectid ray-finned fish from the Late Cretaceous Muwaqqar Chalk-Marl Formation of Jordan.

[1] The holotype, consisting of the skull, pectoral fins, five cervical vertebrae and several scales,[1] was mined from the chalk deposits at Wadi Harrana, Jordan where a lagerstätte known as the Muwaqqar Chalk-Marl Formation is present.

[1] Postredectes is characterized by the absence of large premaxillary tusks, and the premaxillary, maxillary and mandibular teeth were sharp and equipped with two keels, and occupied sockets in both the premaxilla and the maxilla.

The mandibular teeth were also three times longer than those present in the premaxilla and maxilla.
