The 2019 CMLL Día de Muertos was a lineup of two professional wrestling supercard events, scripted and produced by the Mexican Lucha Libre promotion Consejo Mundial de Lucha Libre (CMLL), held to celebrate the Mexican Day of the Dead. The shows took place on November 1 and November 3, 2019, in CMLL's main venue, Arena México, in Mexico City, Mexico. Many of the wrestlers working the shows wore traditional Día de Muertos face and body paint for the event. Losing wrestlers from each show were dragged to El Inframundo ("The Underworld"; in actuality a side entrance in the arena) by a group of wrestlers dressed up as minions of the ruler of the underworld. It was the sixth annual Día de Muertos celebration hosted by CMLL.
As part of the shows, Sansón defended the Rey del Inframundo ("King of the Underworld") championship that he won at the 2017 Día de Muertos show and successfully defended on the 2018 show. The November 3 show featured a Singles match between Micro-Estrellas Microman and Chamuel.
