The Cheval Gauvin (French : Gauvin horse) is a legendary evil horse of Franche-Comté, France and the Jura Mountains in Switzerland. It is said to frequent watercourses, forests or cemeteries and to kill those who mount it by drowning them or throwing them into chasms.
The horse is mentioned close to Chamblay by Désiré Monnier from 1854. It is a harbinger of death, and appears to have been a kind of bogeyman for children. Possibly a transformed lutin (hobgoblin) it is one of a number of legendary horses of Jura. Jean-Louis Thouard depicted it in 1996.
