Deuterostomes are a nephrozoan superphylum of bilaterian animals, a taxon above the level of phylum. It is not part of the usual system of classification.

They are bilateral animals, and are contrasted with the protostomes. Deuterostomes are distingued by their embryo: in deuterostomes, the first opening (the blastopore) becomes the anus, while in protostomes it becomes the mouth.
