The Rába (German: Raab; Hungarian: Rába; Slovene: Raba [ˈráːba];Prekmurje dialect: Rába) is a river in southeastern Austria and western Hungary and a right tributary of the Danube. 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. 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 Slovenes, living in the Rába Valley (Sln. Porabje, Hung. Vendvidék), are the westernmost group of Hungarian Slovenes. The Raba Valley is part of the wider region of Prekmurje.
