El Castillo del Terror (2010) was a major annually occurring professional wrestling event produced by the International Wrestling Revolution Group (IWRG) that took place on November 4, 2010. The event was the tenth show held under the El Castillo del Terror banner, with the first taking place in 2000. The main event was the eponymous Castillo del Terror (Spanish for "Castle of Terror") Steel cage match where the last person eliminated would be forced to take off his mask per the match stipulation.

Starting as far back as at least 2002, the Mexican wrestling promotion International Wrestling Revolution Group (IWRG; Sometimes referred to as Grupo Internacional Revolución in Spanish) has held several annual events where the main event was a multi-man steel cage match where the last wrestler left in the cage would be forced to either remove their wrestling mask or have their hair shaved off under Lucha de Apuestas, or "bet match", rules. From 2005 IWRG has promoted a fall show, around the Mexican Day of the Death, under the name El Castillo del Terror ("The Tower of Terror") to distinguish it from other Steel cage matches held throughout the year such as the IWRG Guerra del Golfo ("Gulf War"), IWRG Guerra de Sexos ("War of the Sexes") or IWRG Prison Fatal ("Deadly Prison") shows. The Castillo del Terror shows, as well as the majority of the IWRG shows in general, are held in "Arena Naucalpan", owned by the promoters of IWRG and their main arena. The 2010 Castillo del Terror show was the sixth year in a row that IWRG promoted a show under that name.
