Xavier Guerrero (December 3, 1896 San Pedro de las Colonias, Coahuila – June 29, 1974 Mexico City) was one of the pioneers of the Mexican muralism movement in the early 20th century.
He learned painting working with his father, who worked in masonry and decorating, with evidence that his ability was mostly self-taught.
In 1912, he moved to Guadalajara and began painting murals, moving to Mexico City in 1919 just as the muralism movement was about to begin.
Most of his work was in collaboration with or subordinate to other painters such as Diego Rivera and David Alfaro Siqueiros, working at the San Ildefonso College, the SecretarÃa de Educación Pública building and the Universidad Autónoma de Chapingo; however, much of his other work has been lost.
While best known for his mural work, his later canvas work is considered to be better.
