Jorge Luis Rivera (born February 28, 1972) is a retired American mixed martial artist who competed in the Middleweight division.

Rivera was defeated by Chris Leben by technical knockout before appearing on The Ultimate Fighter 4 as a Middleweight contestant.

Jorge broke his jaw from the knockout punch and did not compete until UFC 80, where he knocked out heavy favorite Kendall Grove in the first round.

He went 4–3 after the upset, with wins over Eric Schafer, Nate Quarry, Nissen Osterneck and submission artist Rob Kimmons, with his only losses since coming from top level opponents Martin Kampmann, Michael Bisping, and Costas Philippou.

Rivera was scheduled to face Alessio Sakara on August 28, 2010 at UFC 118,[5] but was forced off the card with an arm injury[6] and replaced by Gerald Harris.

On August 5, 2008, his oldest daughter Janessa Marie died unexpectedly from a reaction to prescription medication.
