Guernica is a large 1937 oil painting on canvas by Spanish artist Pablo Picasso. One of Picasso's best known works, Guernica is regarded by many art critics as one of the most moving and powerful anti-war paintings in history, It is exhibited in the Museo Reina Sofía in Madrid.

The gray, black, and white painting, which is 3.49 meters (11 ft 5 in) tall and 7.76 meters (25 ft 6 in) across, portrays the suffering of people and animals wrenched by violence and chaos. Prominent in the composition are a gored horse, a bull, screaming women, dismemberment, and flames.

Picasso painted Guernica at his home in Paris in response to the bombing of Guernica, a Basque Country town in northern Spain, by Nazi Germany and Fascist Italy at the request of the Spanish Nationalists. Upon completion, Guernica was exhibited at the Spanish display at the 1937 Paris International Exposition and then at other venues around the world. The touring exhibition was used to raise funds for Spanish war relief. The painting soon became famous and widely acclaimed, and it helped bring worldwide attention to the Spanish Civil War.
