Provincial elections were held in 15 of the country's 24 provinces in 2025. The elections renewed half of the provincial legislatures and elected governors in Corrientes and Santiago del Estero. According to incomplete official results, the opposition Homeland Force gained 13 more points compared to Javier Milei's La Libertad Avanza. The number of seats to be renewed varied by province. Some have bicameral legislatures, requiring the election of provincial deputies and senators, and others have unicameral legislatures. Chubut, Córdoba, Entre Ríos, La Pampa, Neuquén, Río Negro, San Juan, Santa Cruz, Santa Fe, Tierra del Fuego, and Tucumán did not elect any provincial institutions, although Chubut did hold a referendum.

Results Juan Pablo Valdés of the Civic Radical Union (UCR) was elected governor of Corrientes with 51,9% of the votes by the ruling coalition Vamos Corrientes. La Libertad Avanza consolidated politically, winning Buenos Aires City and Chaco (in alliance with the UCR), and finishing second in several provinces. The provincial parties demonstrated their relevance by winning in Santa Fe, Salta, Jujuy, San Luis, Misiones, and Corrientes. The Homeland Force had poor results in most provinces but won Formosa and Buenos Aires Province by a wide margin.
