The Peruvian resistance movement was composed of the Peruvian militias and guerrillas commanded by local, civilian or military leaders, who confronted the Chilean Army and Navy during the period of occupation that took place during the War of the Pacific.

Despite not having an official founding date, the movement began to function after the occupation of Lima, reaching its peak during the Breña campaign. The resistance was the joint formation of Peruvian montonera forces and troops of the Peruvian Army at the service of Nicolás de Piérola, Andrés Avelino Cáceres and Justiniano Borgoño Castañeda. Miguel Iglesias and his army, as well as the occupation forces of Patricio Lynch and the Chilean Army and Navy in general were the resistance's main enemies.
