Rudiobus is a Celtic god known only from a single inscription, on a bronze figurine of a prancing horse: "sacred to the god Rudiobus". This figurine is one a group found at Neuvy-En-Sullias (Loiret). Horses were linked to many other Celtic deities, including the sky-god and the Celtic version of Mars. The name "Rudiobus" may refer to the colour red.
