Juan Vázquez de Mella y Fanjul (1861–1928) was a Spanish politician and a political theorist. He is counted among the greatest Traditionalist thinkers, at times considered the finest author of Spanish Traditionalism of all time. A politician active within Carlism, he served as a longtime Cortes deputy and one of the party leaders. He championed an own political strategy, known as Mellismo, which led to secession and formation of a separate grouping.
