The Grupo de São Paulo is a political forum established in 1990, primarily composed of leftist political parties and movements from Latin America and the Caribbean. It was created to promote regional integration and cooperation among progressive forces, countering the influence of neoliberal policies in the region. The group originated in São Paulo, Brazil, and has played a significant role in shaping leftist politics in Latin America. It includes notable members such as Partido dos Trabalhadores (PT) and Movimiento 5 Estrellas (M5S), fostering dialogue and collaboration on social, economic, and political issues across member countries.
