A referendum on the approval of the Catalan Statute of Autonomy was held in Catalonia on Thursday, 25 October 1979. Voters were asked whether they ratified a proposed Statute of Autonomy of Catalonia bill organizing the provinces of Barcelona, Gerona, Lérida and Tarragona into an autonomous community of Spain. The final draft of the bill had been approved by the Catalan Assembly of Parliamentarians on 29 December 1978, and by the Congress of Deputies on 13 August 1979, but it required ratification through a binding referendum and its subsequent approval by the Spanish Cortes Generales, as established by Article 151 of the Spanish Constitution of 1978. The referendum was held simultaneously with a similar vote in the Basque Country.
