Nuevo Ideario Nacional is a 1929 insurrectionist proclamation made by young intellectuals of Paraguay that called for a social revolution to create an anarcho-syndicalist society.
Nuevo Ideario Nacional and its opposition, the Liga Nacional Independiente were the major intellectual forces of Paraguay's Liberal Period. The movement climaxed with the failed Taking of Encarnación in February 1931, which failed in conjunction with an aborted construction worker-led general strike in Asunción. The utopianism of Nuevo Ideario Nacional gradually dissipated in favor of more immediate politics, including rising interest in Marxism among the proclamation's adherents in the 1930s. Two of the proclamation's signatories would later lead the Partido Comunista Paraguayo.
