The Cuban Literacy Campaign (Spanish: Campaña Nacional de Alfabetización en Cuba) was a year-long effort to abolish illiteracy in Cuba after the Cuban Revolution. It began on January 1 and ended on December 22, 1961, becoming the world's most ambitious and organized literacy campaign. In 2011, producer and director Catherine Murphy released the 33-minute documentary Maestra about the Cuban Literacy Campaign. The film includes interviews with volunteers who taught during the campaign and archival footage from 1961.
