The Natuna Island surili (Presbytis natunae) is a species of primate in the family Cercopithecidae.
The species is endemic to the Indonesian island of Natuna Besar. It was separated from P. siamensis by Groves in 2001.
A study published in 2003 estimates the population to be less than 10,000 as of 2002, the main threat being heavy logging since 1980.
