Nayato Fio Nuala (real name Yato Fio Nuala) was born in Bireuen, Aceh, February 20, 1968, is an Indonesian film director. He is known as the most productive filmmaker in Indonesia -- 13 of his films were made in the year 2010 alone.

Nayato is infamous for using pseudonyms in his works, using fake names such as Koya Pagayo, Ian Jacobs, and Pingkan Utari. He used his assistant's name Chiska Doppert to credit himself in at least 3 of his films. Furthermore, from his first feature film The Soul (2003), "Dharma You" is often accredited as cinematographer in his films, when in fact it is Nayato himself. Because of this unpredictable nature of his and the lack of film reporting, it is difficult to pinpoint each contribution within his films.
