Renato Naranja (born September 24, 1940) is an International Master of chess from the Philippines.
He also placed first in the 1969 Asian Zonal Tournament in Singapore and subsequently qualified for the 1970 Palma de Mallorca Interzonal on tiebreaks, after drawing his two-game play-off match with co-winner Walter Browne.
While Naranja finished 21st in the 24-player field at Palma, he drew against runaway victor Bobby Fischer, as well as Lajos Portisch and Vasily Smyslov (both of whom failed to qualify for the world championship Candidates Matches by one half-point).
One of Naranja's five wins at Palma was against Samuel Reshevsky.
Naranja migrated in U.S. where he works as a computer programmer and where he frequents the Marshall Chess Club, New York.
