Valencian Union was a regionalist political party in the Valencian Community, Spain.

Valencian or the Valencian language is the official, historical and traditional name used in the Valencian Community of Spain to refer to the Romance language also known as Catalan, either as a whole or in its Valencia-specific linguistic forms. The Valencian Community's 1982 Statute of Autonomy and the Spanish Constitution officially recognise Valencian as the name of the regional language.
