Sjumandjaja (5 August 1934 – 19 July 1985) was an Indonesian director, screenwriter, and actor. During his career he wrote numerous films, directed fourteen, acted in ten, and produced nine; he also won five Citra Awards from the Indonesian Film Festival. His films reflected social realism.
Sjumandjaja was born in Batavia (modern day Jakarta), Dutch East Indies, and grew up there. During high school, he became interested in creative writing and acting, eventually joining the Senen Artists' Group. In 1956, when one of his short stories was adapted into a film, Sjumandjaja became active in the filmmaking industry, writing two films for the production company Persari. After receiving a government scholarship, he moved to Moscow and attended the All-Union State Institute of Cinematography. Upon returning to Indonesia in 1965, Sjumandjaja took a job at the Ministry of Information and continued writing screenplays. In 1971, after leaving the ministry, he directed his first feature film, Lewat Tengah Malam (Past Midnight). He continued to write and direct films until his death from a heart attack on 19 July 1985.
Reportedly a strict director, Sjumandjaja valued creative value over receiving a director's fee. He married three times and had three children, two with his first wife and one with his second. His son, Sri Aksana, is the former drummer of Dewa 19, and his daughter Djenar Maesa Ayu is also a Citra Award-winning director.
