The Socialism and Liberty Party ( , PSOL ) is a left-wing political party in Brazil. The party describes itself as socialist and democratic. The party leader is Juliano Medeiros and the federal deputies Ivan Valente, Marcelo Freixo, Talíria Petrone, Sâmia Bomfim, Áurea Carolina, Edmilson Rodrigues, Fernanda Melchionna, David Miranda, Glauber Braga and Luiza Erundina, with a number of well-known Brazilian left-wing leaders and intellectuals, such as Guilherme Boulos, , Hamilton Assis, Michael Löwy, Luciana Genro, , , , , , João Machado, and others.
