Sandinista ideology or Sandinismo is a series of political and economic philosophies instituted by the Nicaraguan Sandinista National Liberation Front throughout the late twentieth century. The ideology and movement acquired its name, image and most crucially, its military style from Augusto César Sandino, a Nicaraguan revolutionary leader who waged a guerrilla war against the United States Marines and the conservative Somoza National Guards in the early twentieth century. Despite using the Sandino name, the principals of modern Sandinista ideology were mainly developed by Carlos Fonseca, inspired by the leaders of the Cuban Revolution in the 1950s, sought to inspire socialist populism among Nicaragua's peasant population.

The PSN claimed to be a "pure" Marxist group that was committed to fostering mass support of the proletariat and participating in elections before agreeing to any type of revolution. While the FSLN and PSN had been aligned at first, this alliance broke due to the PSN refusing to take on Sandino's image because he had originally refused to embrace Marxism, and the FSLN leaders disagreeing with the PSN and Conservative association. In the mid-1960s, the FSLN failed at their revolutionary attempts by using Che Guevara's foco model, which stated that under the correct repressive and alienating economic and political conditions of the rural population, a small armed movement
