Action for the Republic (Spanish: Acción por la República) is a conservative liberal political party in Buenos Aires, Argentina.

Founded in 1997 by Domingo Cavallo, Harvard University graduate liberal economist and defender of neoliberal ideologies, it became the third party in the 1999 elections.

[7] When Cavallo joined the De la Rúa´s government in 2001, many of the members of the party became part of the Ministry of the Economy.

It closed an agreement with Gustavo Béliz to form an opposition and anti-Menemist front that will aim to change the agenda of state priorities with a view to 1999: they will raise the flag of justice, security and the fight against corruption.

New Leadership, on the other hand, held the candidacies for Buenos Aires legislators with Beliz as the first candidate, seconded by the former Minister of Labor Enrique Rodríguez.
