Jacobulus is an extinct genus of prehistoric marine ray-finned fish that lived during the Early Triassic epoch. It contains a single species, J. novus, known from what is now northern Madagascar during the Olenekian stage. It was a small fish less than 10 centimetres (3.9 in) in length. and appears to have been a grazer-detritivore.
