2023 Buenos Aires provincial election

General elections were held in Buenos Aires Province on 22 October 2023, alongside national elections. The governor and vice governor, as well as half of the Chamber of Deputies and a half of the Senate were renewed. In addition, the municipal offices in the 135 partidos were renewed as well.

The candidacies of each major coalition were defined in the open, simultaneous, and mandatory primaries (PASO), which took place on 13 August 2023. Lists that won at least 1.5% of the votes (including blanks) qualified to the general election.

Incumbent governor Axel Kicillof, of Union for the Homeland (UP), was re-elected to a second term with 44.88% of the vote. Analysts pointed to Kicillof's successful re-election bid as a major factor in bolstering the shock victory of UP presidential hopeful Sergio Massa in the first round of the country's presidential elections.
