Joaquim de Sousa Andrade, better known by his pseudonym Sousândrade[1] (July 9, 1833 – April 20, 1902), was a Brazilian poet, adept of the "Condorist" movement.

He travelled to many countries, such as France (where he graduated in Linguistics and mining engineering at Sorbonne) and the United States, where he settled in 1871.

It was while in the U.S.A. that he wrote Guesa, an epic poem based on a [Muisca] legend about a teenager Indian who is going to be sacrificed to the Sun God.

Guesa is characterized by the employment of neologisms and vertiginous metaphors; thus, it is considered by some critics a precursor work of Modernism, however this was only acknowledged decades after his death.

Returning to Maranhão, in order to commemorate the proclamation of the republic in Brazil, he became president of the mayor's office of São Luís in 1890.
