Nepenthes diatas ( /nɨˈpɛnθiːz daɪˈætəs/; from Indonesian: diatas = above, on top) is a tropical pitcher plant endemic to Sumatra, where it grows at an altitude of between 2400 and 2900 m above sea level.
Nepenthes diatas was formally described in 1997 by Matthew Jebb and Martin Cheek in their monograph "A skeletal revision of Nepenthes (Nepenthaceae)", published in the botanical journal Blumea. However, the name N. diatas had already been in use since at least 1994.
No forms or varieties of N. diatas have been described.
