Juan José Paz (born September 24, 1980 in Santa Cruz de la Sierra) is a Bolivian judoka, who competed in the men's half-lightweight category.
Paz qualified as a lone judoka for the Bolivian squad in the men's half-lightweight class (66 kg) at the 2004 Summer Olympics in Athens, by granting a tripartite invitation from the International Judo Federation.
He conceded his opening match with a single shido penalty and succumbed to a single leg takedown (kuchiki taoshi) and a 1–0 score on waza-ari from Australia's Heath Young after five minutes of regulation.
