The Rey de Reyes (English: "King of Kings") 2008 was the twelfth annual Rey de Reyes professional wrestling tournament and show show promoted by Asistencia Asesoría y Administración (AAA). The event took place on March 18, 2007 in the Plaza de Toros Lorenzo Garza arena in Monterrey, Nuevo León, Mexico. The main focus of the 2008 Rey de Reyes show was the twelfth annual Rey de Reyes tournament and a match between the top Technico Cibernético and the Rudo El Mesias for the AAA World Heavyweight Championship which El Mesias held going into the event. The undercard saw 4 qualifying matches for the Rey de Reyes leading to the traditional 4 man elimination match that leads to a new Rey de Reyes being crowned. The undercard also saw the continuing feud between Konnan’s La Legión Extranjera (Foreign Legion) and their altercations with wrestlers defending AAA. For this even La Legión Extranjera brought in two American wrestlers (Sabu and Scott Steiner) to strengthen their side. The other under card storyline was that of Los Psycho Circus (a trio of Rudo wrestlers dressed up as clowns) working a storyline with The Black Family.
The event featured ten of professional wrestling matches with different wrestlers involved in pre-existing scripted feuds or storylines. Wrestlers portray either villains (referred to as Rudos in Mexico) or fan favorites (Técnicos in Mexico) as they compete in wrestling matches with pre-determined outcomes.
