The Peruvian Aprista Party (Spanish: Partido Aprista Peruano, PAP) (listen ) is a Peruvian political party and a member of the Socialist International. The party was founded as the American Popular Revolutionary Alliance (APRA) by Víctor Raúl Haya de la Torre, who originally intended to create a network of anti-imperialist social and political movements in Latin America. Members are called "companions", based on the fraternity espoused by Haya de la Torre. Originally a centre-left to left-wing party with democratic socialist and nationalist elements (in addition to the aforementioned anti-imperialism), the party moved closer to the political centre under the leadership of Alan García starting in the 1980s, embracing social democracy and later some Third Way policies.

Founded continentally in 1924 in Mexico City, Mexico, and nationally in 1930 in Lima, it is one of the oldest political parties in Latin America. Among the Peruvian political parties in activity, specifically for having been stripped of electoral victories by coups or military governments after having triumphed democratically, it also went through two long periods of illegality, both under military and civilian governments, having been persecuted by the presidencies of Luis Miguel Sánchez Cerro and Manuel A. Odría. The Peruvian Aprista Party has gained in the presidency in two occasions: in 1985 and 2006, both under the candidacy of Alan García. In the extraordinary congressional elections of 2020, held after the dissolution of Congress in 2019, the APRA had its worst electoral result of 2.7%, failing to pass the 5% electoral threshold, which means that it would not have parliamentary representation for the first time in 25 uninterrupted years.Although APRA does not operate throughout Latin America as its founder envisioned for, it has served as a powerful influence for other progressive Latin American political organizations, such as Democratic Action (AD) in Venezuela and the Socialist Party of Chile.
