The Walloon Rally (French: Rassemblement wallon, pronounced [ʁasɑ̃bləmɑ̃ walɔ̃]; RW) is a regionalist[1] political party in Belgium, active in Wallonia since 1968.

Founded on 7 March 1968, the party contested the Belgian general election of 1968 in a coalition with the FDF, a Brussels-based francophone political party, receiving 5.9% of the vote nationally.

A split in the early 1980s created the Walloon Popular Rally, a more left-wing grouping, which later merged with the Socialist Party.

The Wallonia-France Rally, which supports the union of Wallonia and France, was formed by the rump of the party's membership in 1999.

In 2010, Union For Wallonia, which took part in June federal elections under the name W+, was renamed Walloon Rally, which was its largest component.
