The karbovanets (Ukrainian:карбованець, karbovanets, plural: карбованці, karbovantsi for 2–4, or карбованців, karbovantsiv for 5 or more), also known at one point as koupons or coupons, has been a distinct unit of currency in Ukraine during three separate periods. The name is also used in the Ukrainian language for the Imperial ruble and the Soviet ruble, but not for the modern Russian ruble.
