Santiago Vaca Guzman (Sucre, c. 1847 – Buenos Aires, 1896) was a Bolivian writer.
He trained as a lawyer and worked as a journalist, founding the newspaper La Patria in Sucre in 1871.
As a writer, he published both fiction and poetry.
His novel Su excelencia y su ilustrisima[1] is regarded as one of the finest in Bolivian literature.
His political stance against the caudillos Mariano Melgarejo and Agustin Morales forced him to go into exile.
