Juan Carlos Jacinto Jiménez (born July 2, 1978) is a Dominican judoka, who played for the extra and half lightweight categories.

At the 2004 Summer Olympics in Athens, Jacinto switched to a heavier class by competing in the men's half-heavyweight division, despite weighing 68 kilograms.

He lost again in his first preliminary match to Kazakhstan's Muratbek Kipshakbayev this time, by a waza-ari (half-point) and a sukui nage (double leg takedown).

He received a bye for the second preliminary match, before losing out by an automatic ippon to Japan's Masato Uchishiba, who eventually won a gold medal in this event.
