Mexican muralism is a Mexican art movement that primarily took place from the 1920s and 1930s. The muralists work can be described as predominantly a social realist style, however the artists also did not refrain from including influences from the contemporary European Avant-garde movements (Cubism, Futurism, Expressionism, Postimpressionism, Surrealism and neoclassicism), as well as mural Italian renaissance mural technique. The proponents of the style, namely the Minister of Education José Vasconcelos, did not stipulate the subject matter or formal elements of the style, however most of the muralists explored nationalistic subject matter, drawing on Mexico's pre-columbian culture, the Mexican people and their heroes.

Similarly to the goals of Social Realism in Europe, especially Socialist Realism, the Mexican muralists sought a didactic style that would be sufficient to communicate the ideals of the new Alvaro Obregón government.

The principal artists in the muralist movement where Diego Rivera, José Orozco and David Alfaro Siqueiros.
