The Neva is a river in northwestern Russia flowing from Lake Ladoga through the western part of Leningrad Oblast (historical region of Ingria) to the Neva Bay of the Gulf of Finland. Despite its modest length of 74 kilometres (46 mi), it is the fourth-largest river in Europe in terms of average discharge (after the Volga, the Danube and the Rhine).
