The IWRG Junior de Juniors Championship is a professional wrestling championship promoted by the Mexican lucha libre promotion International Wrestling Revolution Group (IWRG) since February 2011. The championship is only for second or third generation wrestlers; this includes wrestlers with storyline relationships such as El Hijo del Espectro Jr., who is not related to Espectro Jr. in real life but is paying for the use of the name. IWRG never revealed how Oficial Factor qualified as a second generation wrestler.
