Jackson de Figueiredo Martins (born 9 October 1891 in Aracaju, Brazil - died 4 November 1928 in Rio de Janeiro, Brazil) was a Brazilian lawyer, intellectual and journalist.
Jackson de Figueiredo was a very well-known intellectual and journalist in Brazil. In 1909, Figueiredo began his academic studies in a faculty of law in Salvador, where he establish residence. In 1913 he concluded the course and the following year went to live in Rio de Janeiro. Motivated by the 1916 pastoral letter by Bishop of Olinda Sebastiao da Silveira Cintra, he converted to Catholicism in 1918. His conversion created a sensation and was the reference point of the Brazilian Catholic laity. It was also the decisive impetus for the formation of a conservative political Catholicism in Brazil. With this intention, and encouraged by Bishop Leme da Silveira, in 1922 he founded the Centro Dom Vital, named after the late Bishop of Olinda Vital Gonçalves Maria de Oliveira, and in 1921 the magazine A Ordem (The Order). With these two he opposed Communism and Liberalism of his time.
He died in 1928 in Rio de Janeiro, but his influence continued and eventually led to the founding in 1932 of the League Electoral Católica as a Catholic representation for the Constituent Assembly, which President Getúlio Dornelles Vargas summoned.
