The Elbe (ˈɛlbə; Labe ˈlabɛ; Ilv or Elv; Upper and Łobjo) is one of the major rivers of Central Europe. It rises in the Giant Mountains of the northern Czech Republic before traversing much of Bohemia (western half of the Czech Republic), then Germany and flowing into the North Sea at Cuxhaven, northwest of Hamburg. Its total length is .
The Elbe's major tributaries include the rivers Vltava, Saale, Havel, Mulde, Schwarze Elster, and Ohře.
The Elbe river basin, comprising the Elbe and its tributaries, has a catchment area of , the twelfth largest in Europe. The basin spans four countries; however, it lies almost entirely just in two of them, Germany (65.5%) and the Czech Republic (33.7%, covering about two thirds of the state's territory). Marginally, the basin stretches also to Austria (0.6%) and Poland (0.2%). The Elbe catchment area is inhabited by 24.4 million people, the biggest cities within are Berlin, Hamburg, Prague, Dresden and Leipzig.
First attested in Latin as Albis, the name Elbe means "river" or "river-bed" and is nothing more than the High German version of a word (*albī) found elsewhere in Germanic; cf. Old Norse river name Elfr, Swedish älv "river", Norwegian elv "river", Old English river name elf, and Middle Low German elve "river-bed".
The Elbe (Labe) rises on the slopes of Mt. Violík at an elevation of in the Giant Mountains on the northwest borders of the Czech Republic. Of the numerous small streams whose waters compose the infant river. After plunging down the of the Elbe Falls, the latter stream unites with the steeply torrential Bílé Labe, and thereafter the united stream of the Elbe pursues a southerly course, emerging from the mountain glens at Jaroměř, where it receives Úpa and Metuje.
Here the Elbe enters the vast vale named Polabí (meaning "land along the Elbe"), and continues on southwards through Hradec Králové (where Orlice flows in) and then to Pardubice, where it turns sharply to the west. At Kolín some further on, it bends gradually towards the north-west.
