Valencian Socialist Action (in Valencian: Acció Socialista Valencià) was a political party in Valencia, Spain. It existed informally between 1962 and 1964, during the Francoist State, which had banned all the political organizations other than those in the Movimiento Nacional.
The party was founded by ex-members of the Social Christian Movement of Catalonia, including Eliseu Climent i Corberà, Joan Francesc Mira i Casterà, Rosa Raga and Vicent Àlvarez i Rubio. The party was heavily influenced by the ideas of Joan Fuster, and defended the Catalan Countries. Its members joined the Valencian Socialist Party in late 1964.
