Jon Sobrino SJ (born 27 December 1938) is a Spanish Jesuit Catholic priest and theologian, known mostly for his contributions to Latin American liberation theology.

The Jesuits were targeted for their outspoken work to bring a resolution to the brutal El Salvador Civil War that left about 75,000 men, women, and children dead, mostly civilians.

Investigated by the Vatican throughout his career as a professor of theology, he has remained an outspoken proponent of peace, joining protests in 2008 of the continued training of Latin American military officers in torture techniques at the School of the Americas at Fort Benning.

[6] Supported by more than 100 professors of Catholic theology, Hünermann also demanded an "intelligent redevelopment" of the Vatican Congregation for the Doctrine of the Faith, because, as successor organization of the Holy Office, it still had the structure of an "early modern board of censors".

[7] Sobrino's work was reviewed by a number of theologians, including Bernard Sesboüé [fr], José Ignacio González Faus [es], Javier Vitoria, Carlo Palacio of Belo Horizonte, and Martin Maier, editor of the German Jesuit periodical Stimmen der Zeit.
