The 2002 El Castillo del Terror (Spanish for "The Tower of Terror") was a major lucha libre event produced and scripted by the Mexican International Wrestling Revolution Group (IWRG) professional wrestling promotion on October 31, 2002. The 2002 El Castillo del Terror was the second ever IWRG El Castillo del Terror event held. The main event was the eponymous Castillo del Terror (Spanish for "Tower of Terror") Steel cage match where the last person eliminated would be forced to take off his wrestling mask or have his hair shaved off as a result of the loss.

Due to incomplete records of the show the only known results state that Mega was listed as the winner of the El Castillo del Terror main event while Karma lost the match and thus had to unmask and reveal that he was actually Ari Romero under the mask. The remaining results have not been found in documentation.

Starting in the year 20002005 IWRG has promoted a fall show, around the Mexican Day of the Death, under the name El Castillo del Terror ("The Tower of Terror"), creating an annual event on their major show calendar that has been held almost every year since 2000. The 2002 El Castillo del Terror show was the second overall show under that name, with IWRG not holding a Castillo del Terror in 2001.
