List of political parties in Argentina


This article lists political parties in Argentina.
Argentina has a multi-party system with two strong political parties or alliances, and various smaller parties that enjoy representation at the National Congress.
Since the 1990s, there is a strong decentralizing tendency within the national parties, along with the growing national relevance of province-level parties and alliances. In the last decade, most of the newly formed parties remained as junior partners of the main alliances or as district-level relevant political forces.

Historic background

From the "national organisation" process up to 1916, the oligarchic National Autonomist Party directed Argentine politics, before being replaced, through the first secret ballot elections, by the Radical Civic Union. The "Infamous Decade", initiated by the first modern coup d'état in Argentina, represented a return of the conservatives, who implemented a so-called "patriotic fraud" electoral practice. Since 1946, the strongest party has been the Justicialist Party, emerging around the leadership of Juan Perón. From 1946 to 2001, the second most important party was the Radical Civic Union, until the 2001 financial crisis. From then on, left-wing Justicialists Néstor Kirchner and his wife Cristina Fernández de Kirchner won the 2003, 2007 and 2011 general elections. After that, in the 2015 general election, Kirchnerism was defeated by a Centre-right coalition, Cambiemos, composed of the Radical Civic Union and Republican Proposal, a new liberal conservative party. However, in the elections of 2019, the Justicialist Party joined the Frente de Todos which won the presidential elections. The PJ returned to power, with Alberto Fernández as President of the Nation.
Since 10 December 2023, the current-ruling party in Argentina is the Libertarian Party, with Javier Milei as President of the Nation.
