Apantesis ornata, the ornate tiger moth or achaia moth, is a moth of the family Erebidae. It was described by Alpheus Spring Packard in 1864. It is found in western North America from southern British Columbia through the Pacific Northwest to southern California, northern Utah, and western Wyoming and Montana.
