The Rouen duck (Anas platyrhynchos domesticus) gets its name from the city of Rouen, France, its place of origin, though it's also called Rouen Foncé (Dark Rouen) in France – distinguishing it from a lighter variety (Rouen Clair). While linked to Rouen, its name may have evolved from earlier terms like "Rhone" or "Roan" (referencing its colour/pattern) before stabilizing on the city's name, as it was developed from large, domestic Mallards for meat in Normandy, a region famous for poultry. Rouen ducks are a domesticated breed found in many parts of the world.
