Its source is in Austria, some kilometres east of Bruck an der Mur below Heubodenhöhe Hill. It flows through the Austrian states of Styria and Burgenland, and the Hungarian counties of Vas and Győr-Moson-Sopron. Its is 298.2 km (185.3 mi) long, of which about 100 km in Austria. It flows into a tributary of the Danube (Mosoni-Duna) in northwestern Hungary, in the city of Győr. Towns along the Rába include Gleisdorf, Feldbach (both in Austria), and Szentgotthárd and Körmend (in Hungary). In the early Cenozoic the river used to flow in the opposite direction, but tectonic uplift reversed this flow.
The Rába was attested as Latin Arrabo and Greek Arabon (Ἀραβον) in antiquity, as Raba and Hrapa in AD 791, and as ad Rapam in 890. The various modern names of the river are derived from the Romance reflex Rābo. The name is probably Indo-European, but its origin is unknown.
