2015 Argentine general election

General elections were held in Argentina on 25 October 2015 to elect the President and National Congress, and followed primary elections which were held on 9 August 2015. A second round of voting between the two leading candidates took place on 22 November, after surprisingly close results forced a runoff. On the first runoff voting ever held for an Argentine Presidential Election, Buenos Aires Mayor Mauricio Macri narrowly defeated Front for Victory candidate and Buenos Aires Province Governor Daniel Scioli with 51.34% of votes. Macri's vote count of nearly 13 million votes made it the highest number of votes any candidate has ever received in Argentinian history, until Javier Milei obtained over 14 million votes in the second round of the 2023 presidential election. He took office on 10 December, making him the first freely elected president in almost a century who was not either a Radical or a Peronist.

Macri performed better among higher-income provinces in the central area of the country, while Scioli performed strongly in poorer provinces in the northwest, the northeast and Patagonia.
