Doryaspis is an extinct genus of armored jawless fish belonging to the order Pteraspidiformes. It contains five species, all of which are exclusively known from what is now the island of Spitsbergen in the Svalbard archipelago of Norway. The genus lived during the Pragian to Emsian ages of the Early Devonian period. Doryaspis is distinguished from other pteraspidiforms by several unusual features, most notably its narrow, outward-pointing cornual plates and a long, pointed projection near its mouth known as a pseudorostrum.
