Roberto Francisco Jimenez is an American-Ecuadorian Brazilian jiu-jitsu black belt, promoted by his father Raul "Gacho" Jimenez at the 2019 No-Gi World Championship after submitting every opponent en route to the brown belt absolute title. A prodigy from his colored-belt days — winning IBJJF Worlds at purple belt in both weight and absolute — Jimenez captured the 2023 IBJJF No-Gi World Championship absolute title and won the 2022 ADCC South America Trials. He is known for an explosive, submission-first style and a willingness to compete well above his natural weight class. Jimenez trains at Studio 76 and took silver at both heavyweight and absolute at the 2025 Pan Championship.
