José Eustasio Rivera (February 19, 1888 - December 1, 1928) was a Colombian politician and writer who worked as a lawyer in the arrangement of the limits between Colombia and Venezuela, when he could visit the flatlands and the tropical jungle, places that greatly influenced his works.

Rivera's short labour as a writer began with Tierra de promisión (1921), which is a compilation of poems writen in a modernist style, and ended with his most known work La Vorágine.
