Spathobatis (from , 'blade' and 'ray') is an extinct genus of rays in the family Asterodermidae from the Jurassic period of Europe.
Spathobatis had a body similar to that of a modern guitarfish, being highly flattened and widened, specializing the creature for a life on the ocean floor. Although it is one of the earliest known fossil rays, it already resembled modern forms in a number of ways. Like them, its eyes and spiracles were located atop the head, its mouth and gill slits were positioned on the underside of the body, and it had greatly expanded pectoral fins for swimming.
