Rába

Next on our list of the longest rivers in Hungary is Rába. The Rába is a right tributary of the Danube that flows through southern Austria and western Hungary. Its source is in Austria, a few kilometers east of Bruck a der Mur, beneath the Heubodenhöhe Hill. It runs across Austria's Styria and Burgenland, as well as Hungary's Vas and Győr-Moson-Sopron counties. It is 247 miles long and is shared with Austria. It flows into a tributary of the Danube in Győr, in northwestern Hungary.

Gleisdorf and Feldbach (both in Austria), as well as Szentgotthárd and Körmend (in Hungary), are towns along the Rába. The river used to flow in the opposite direction in the early Cenozoic, but tectonic uplift reversed its flow. In antiquity, the Rába was mentioned as Latin Arrabo and Greek Arabon, Raba and Hrapa in AD 791, and ad Rapam in 890. The river's contemporary names are derived from the Romance reflex Rābo. The name is most likely Indo-European, although its origin is uncertain.
