Adityavarman (?-1375?) was the first king of Melayu in central Sumatra in what is now Indonesia. He ruled from about 1356 to about 1375.
According to Javanese chronicles, Adityavarman was brought up as a young prince in the Majapahit kingdom in Java. The Javanese took him back to Melayu and made him king, intending to keep him under their control. But once Adityavarman was established, he governed almost as an independent ruler. Adityavarman extended his kingdom from the area of Jambi on the east coast of central Sumatra, to the mountain districts of the Minangkabau people in western central Sumatra. A stone sculpture of Adityavarman stands in the Indonesian National Museum in Jakarta.
