The Túpac Amaru Revolutionary Movement (Spanish: Movimiento Revolucionario Túpac Amaru, abbreviated MRTA) was a Peruvian Marxist-Leninist guerrilla group which started in the early 1980s. Their self-declared goal was to demonstrate to leftist groups in Peru that sought change through the current government the viability of radical revolution. The MRTA also aimed to provide an alternative to the more radical militant group, the Shining Path, which placed them in direct competition. The group was led by Víctor Polay Campos until he was sentenced to 32 years' imprisonment in 1992 and by Néstor Cerpa Cartolini ("Comrade Evaristo") until his death in 1997.

The MRTA took its name in homage to Túpac Amaru II, an 18th-century rebel leader who was himself named after his claimed ancestor Túpac Amaru, the last indigenous leader of the Inca people. The MRTA was designated as a terrorist organization by the Peruvian government, the US Department of State, and the European Parliament but was later removed from the United States State Department list of Foreign Terrorist Organizations on 8 October 2001.

At the height of its strength, the movement had several hundred active members. Its stated goals were to establish a socialist state and rid the country of all imperialist elements.
