Somme-Bionne is a commune in the Marne department in north-eastern France. An important Iron Age chariot burial of 450-300 BC was found in the vicinity of the village in the nineteenth century. The finds from the La Tène period grave came into the possession of the French collector Léon Morel, who sold it, along with his entire antiquities collection from the Champagne region of France, to the British Museum in 1901.
