More than six million registered voters in Andalusia will cast ballots for autonomous community elections on May 17, 2026 [1], [2].

These elections determine the composition of the regional government in southern Spain. High voter turnout is critical for political parties seeking to secure a mandate and influence the direction of regional policy.

The official campaign period began after the elections were called on March 23, 2026 [3]. As the campaign window closes, regional political parties have shifted their focus toward final appeals for citizen participation. Parties said voters should participate in the process to ensure the legitimacy of the resulting administration [1], [2].

Andalusia is one of Spain's most populous autonomous communities. The scale of the electorate, exceeding 6 million people [1], means that small shifts in turnout or voter preference can significantly alter the distribution of seats in the regional parliament.

Logistical preparations for the vote have been underway since the call for elections in March [3]. These preparations include the organization of polling stations, and the processing of mail-in ballots to accommodate the millions of eligible citizens [3].

Political leaders have spent the final days of the campaign emphasizing the importance of the vote. The focus remains on mobilizing the base and attracting undecided voters before the polls open on Sunday [1].

The outcome of the Andalusian elections serves as a significant barometer for political trends within Spain. Because of the region's large population and economic importance, the victory of a specific party or coalition often signals broader shifts in national sentiment that can influence future general elections.
