Simblaspis is an extinct monospecific genus of arthrodire placoderm fish of the Early Devonian period. The type species Aleosteus eganensis was described in 1958, and was found in Pragian strata of the Qasr Limestone in Saudi Arabia.[1]

It is one of the more basal members of the order Arthrodira, closely related to Aleosteus, as shown in the cladogram below:[2]
