2015 Argentine provincial elections

On the 25 October elections numerous provinces also elected governors, with the new ones beginning their terms on 10 December 2015. These provinces were Buenos Aires province, Catamarca, Chubut, Entre Ríos, Formosa, Jujuy, La Pampa, Misiones, San Juan, San Luis and Santa Cruz, encompassing 11 of the country's 23 provinces. The other provinces elected governors in different days of 2015; the only exceptions were Corrientes and Santiago del Estero whose governors' terms were not due to finish in 2015.

María Eugenia Vidal was elected governor of the populous Buenos Aires Province, defeating the controversial Aníbal Fernández; her victory influenced as well the growth of Macri in the presidential elections. Similarly, the unpopular Fernández may have subtracted non-Kirchnerite votes from Scioli. The victory was considered significant given that Fernández is the incumbent Cabinet Chief of the Kirchner administration, and that Vidal is directly replacing Daniel Scioli's current post as governor of the province. It is made more significant as she is the first female governor of the province, and the first non-Peronist governor since 1987. The Republican Proposal also retained the city of Buenos Aires, that elected Horacio Rodríguez Larreta as the new mayor. The PRO stronghold had gone to a second round between Larreta and Martín Lousteau (also of the Cambiemos front, but not in the same party) after the Front for Victory's Mariano Recalde finished third. Juan Schiaretti won the elections in Córdoba, and he is the single governor of the UNA ticket.
