The Republican Party of Puerto Rico (Spanish: Partido Republicano de Puerto Rico) is the local affiliate of the national United States Republican Party in Puerto Rico. The affiliation started in 1903. The party does not participate in the November elections mandated by the Constitution of Puerto Rico for local registered political parties because it is not a registered party in Puerto Rico for local electoral purposes. Instead, the party holds its own elections to select the Puerto Rico delegates to the Republican National Convention and holds presidential primaries on the last Sunday of February.
