José Luis Rodríguez Arellano (born February 21, 1951) is a Mexican Luchador Enmascarado (masked professional wrestler) who wrestles under the ring name Dos Caras (Spanish for "two faces"). His most active years were in the 1970s and 1980s, and he achieved his greatest success in Mexico's Universal Wrestling Alliance (UWA), where he won the UWA World Heavyweight Championship three times. He has been called "the greatest heavyweight ever to come out of Mexico".
Rodríguez made his debut on January 6, 1970 at the age of 18 after training under Rafael Salamanca and Gory Medina. He adopted the ring name Dos Caras upon his debut, wearing a colorful mask with a figure of a two headed eagle on it to reflect his name. Rodríguez later stated that the name and mask was not inspired by the Two-Face comic book character but as a "two faced cheater" character (called a Rudo or Heel in pro wrestling). Through connections with his older brother who had been wrestling as Mil Mascaras for some years when Dos Caras made his debut he quickly landed a regular job with the professional wrestling promotion Empresa Mexicana de la Lucha Libre (EMLL), the world's oldest and Mexico's largest promotion. In the early years he often teamed with another brother who wrestles under the name Sicodélico in low card matches while gaining experience.

Before working for WWE, Rodríguez used the name Dos Caras Jr. as both a mixed martial artist and luchador in Mexico and Japan, achieving success in Consejo Mundial de Lucha Libre (CMLL).
