Lutjanus agennes, the African red snapper, Guinean snapper or African cubera snapper, is a species of marine ray-finned fish belonging to the family Lutjanidae, the snappers. It is native to the coastal Atlantic waters of Africa.

Taxonomy Lutjanus agennes was first formally described in 1863 by the Dutch physician, herpetologist and ichthyologist Pieter Bleeker with the type locality given as "Ashantee in Guinea". Bleeker did not explain the derivation of the specific name but it may be from agenes, which means "of low family", possibly a reference to its similarity to L. modestus, the name modestus meaning the "modest or unassuming one". Bleeker also described L. modestus in 1863 and it is not clear whether this is a synonym of this species or L. endecacanthus.

Description Lutjanus agennes has a relatively deep body with a pointed snout and a rather angular forehead. The mouth extends back to below the centre of the eye. The vomerine teeth are arranged in a triangular patch which may have a posterior extension. The incision and the knob on the preoperculum are not well developed. The dorsal fin has 10 spines and 13–14 soft rays while the anal fin contains 3 spines and 8 soft rays.
