Party of the Democratic Revolution

The Party of the Democratic Revolution (Spanish: Partido de la Revolución Democrática, PRD) is a state-level social democratic political party in Mexico (previously national, until 2024). The PRD originated from the Democratic Current, a political faction formed in 1986 from the Institutional Revolutionary Party (PRI). The PRD was formed after the contested general election in 1988, which the PRD's immediate predecessor, the National Democratic Front, believed was rigged by the PRI. This sparked a movement away from the PRI's authoritarian rule.

As of 2023, the PRD was a member of the Fuerza y Corazón por México (Strength and Heart for Mexico) coalition. Internationally, the PRD was a member of the Progressive Alliance. The members of the party are known colloquially in Mexico as Perredistas. In 2024, the party failed to reach the necessary percentage of votes to keep its registration as a national political party.
