Pengkhianatan G30S/PKI is a 1984 Indonesian docudrama co-written and directed by Arifin C. Noer, produced by G. Dwipayana, and starring Amoroso Katamsi, Umar Kayam, and Syubah Asa. Produced over a period of two years with a budget of Rp. 800 million, the film was sponsored by Suharto's New Order government. It was based on an official history of the 30 September Movement coup in 1965 written by Nugroho Notosusanto and Ismail Saleh, which depicted the coup as being orchestrated by the Communist Party of Indonesia.

The Thirtieth of September Movement was a self-proclaimed organization of Indonesian National Armed Forces members. In the early hours of 1 October 1965, they assassinated six Indonesian Army generals in an abortive coup d'état. Later that morning, the organisation declared that it was in control of media and communication outlets and had taken President Sukarno under its protection. By the end of the day, the coup attempt had failed in Jakarta. Meanwhile, in central Java there was an attempt to take control over an army division and several cities. By the time this rebellion was put down, two more senior officers were dead.
