{{main|List of rivers of Romania}}

After entering the country in the southwest at Bazias, the [[Danube]] travels some 1,075 kilometers (almost 40% of its entire length) through or along Romanian territory, forming the southern frontier with Serbia and Bulgaria. Virtually all of the country's rivers are tributaries of the Danube, either directly or indirectly, and by the time the Danube's course ends in the Black Sea, they account for nearly 40 percent of the total discharge. The most important of these rivers are the [[Mureș River]], the [[Olt River]], the [[Prut]], the [[Siret River]], the [[Ialomița River]], the [[Someș River]], and the [[Argeș River]]. The [[Olt River]] {{convert|615|km|mi}} is the longest river that is fully within Romania's national borders.

Romania's rivers primarily flow east, west, and south from the central crown of the Carpathians. They are fed by rainfall and melting snow, which causes considerable fluctuation in discharge and occasionally catastrophic [[flood]]ing. In the east, river waters are collected by the Siret and the Prut. In the south, the rivers flow directly into the Danube, and in the west, waters are collected by the [[Tisza]] on Hungarian territory.

The Danube is by far Romania's most important river, not only for transportation, but also for the production of [[Hydroelectricity|hydroelectric power]]. One of Europe's largest hydroelectric stations is located at the [[Iron Gates]], where the Danube surges through the Carpathian gorges. The Danube is an important water route for domestic [[Freight transport|shipping]], as well as international trade. It is navigable for river vessels along its entire Romanian course and for seagoing ships as far as the port of [[Brăila]]. A problem with the use of the Danube for inland transportation is its remoteness from most of the major industrial centers. Moreover, marshy banks and perennial flooding impede navigation in some areas.
