Republican Proposal (Spanish: Propuesta Republicana), usually referred to by its abbreviation PRO, is a political party in Argentina. PRO was formed as an electoral alliance in 2005, but was transformed into a national party in 2010. It is led by former Argentine president Mauricio Macri, who has been the party's president since May 2024.

PRO has governed the city of Buenos Aires since 2007 and formed Cambiemos with the Radical Civic Union and the Civic Coalition ARI with which they won the 2015 general election.

Macri re-opened Argentina to international markets by lifting currency controls, restructuring sovereign debt, and pressing free-market solutions.
