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.
