# 1991 Spanish regional elections

The 1991 Spanish regional elections were held on Sunday, 26 May 1991, to elect the regional parliaments of thirteen of the seventeen autonomous communities—Aragon, Asturias, the Balearic Islands, the Canary Islands, Cantabria, Castile and León, Castilla–La Mancha, Extremadura, La Rioja, Madrid, Murcia, Navarre and the Valencian Community—, not including Andalusia, the Basque Country, Catalonia and Galicia, which had separate electoral cycles. 784 of 1,178 seats in the regional parliaments were up for election. The elections were held simultaneously with local elections all throughout Spain.

## Election date

Determination of election day varied depending on the autonomous community, with each one having competency to establish its own regulations. Typically, thirteen out of the seventeen autonomous communities—all but Andalusia, the Basque Country, Catalonia and Galicia—had their elections fixed for the fourth Sunday of May every four years, to be held together with nationwide local elections.
