Guillermo Collazo Tejada (7 June 1850, Santiago de Cuba - 26 September 1896, Paris) was a Cuban painter and advocate for independence.

At the beginning of the Ten Years' War, his parents, aware of his activities and concerned for his safety, hastily put him on board a ship headed for the United States.

[1] He also continued to raise money for revolutionary causes, and helped José Martí get his first writing job at The Hour, a magazine where Collazo worked as an illustrator.

Five years later,[1] hampered by the increasingly oppressive political atmosphere there, he decided to go to Paris, where he opened a large studio which became a meeting point for the Cuban exile community and, occasionally, a place for planning revolutionary activities.

[2] His works were not exhibited in Cuba until 1933, when the architect Evelio Govantes (1886–1981) organized a showing at the Lyceum with paintings borrowed from Collazo's friends and family.
