The NWA World Light Heavyweight Championship was a professional wrestling championship sanctioned by the National Wrestling Alliance (NWA). For the majority of its existence the title was promoted by Mexican promotion Consejo Mundial de Lucha Libre (CMLL), where it was known in Spanish as the Campeonato Mundial Semi Completo de NWA. It began as an official National Wrestling Alliance (NWA) title and was given to the NWA's Mexican affiliate, Empresa Mexicana de Lucha Libre, to control. The title was also promoted in NWA Hollywood Wrestling until Hollywood Wrestling's closure in 1982. The title remained under the control of EMLL even after EMLL pulled out of the NWA and changed its name to Consejo Mundial de Lucha Libre. Due to its history, it was considered one of the most important titles in EMLL/CMLL. As it was a professional wrestling championship, it was not won legitimately; it was instead won via a scripted ending to a match or awarded to a wrestler because of a storyline. The official definition of the light heavyweight weight class in Mexico is between 92 kg (203 lb) and 97 kg (214 lb), but this was not always strictly enforced.

Manuel González Rivera was a Mexican professional wrestler, or Luchador best known under the ring name Dr. Wagner. González made his professional wrestling debut in 1961 and worked the majority of his career for the Mexican professional wrestling promotion Empresa Mexicana de Lucha Libre (EMLL). As Dr. Wagner, he worked most of his career as an enmascarado, or masked wrestler, losing his mask to El Solitario in 1985. Along with Ángel Blanco, González formed one of the premier tag teams of the 1960s and 1970s called La Ola Blanca. One of his sons works as a professional wrestler under the name Dr. Wagner Jr., and another son wrestled as Silver King until his death in 2019. One of his grandsons made his wrestling debut in 2009 under the name El Hijo de Dr. Wagner Jr. or Dr. Wagner III.
