Partíu Asturianista (PAS) is a nationalist political party from Asturias, Spain, founded in 1985 by Xuan Xosé Sánchez Vicente.

After leaving the Spanish Socialist Workers' Party in 1983, X. X. Sánchez Vicente founded the Partíu Asturianista, which was officially legalised in 1985.

Among the primary political targets of the party was a reform of the Asturian Statute of Autonomy, in which Asturias would be recognised as a Historical Nationality, the Asturian language would be granted official status (together with Spanish language), a statute that would guarantee the highest self-government possibilities recognized in the Spanish Constitution of 1978.

The PAS decides then to take part in that year's regional elections, which finally placed the Partíu Asturianista as the fifth political power of Asturias.

The PAS also ran for the European Parliament elections of 1989, being included in a coalition of nationalist parties from all Spain.
