Eduardo "Eddie" Gory Guerrero Lanes was an American professional wrestler born into a Mexican wrestling family. He wrestled in Mexico and Japan and in every major professional wrestling promotion in the United States. He wrestled in the Extreme Championship Wrestling (ECW), World Championship Wrestling (WCW) and in World Wrestling Entertainment (WWE).

Guerrero’s in-ring gimmick was that of a crafty, resourceful wrestler who would do anything to win a match. His catch phrase became Cheat to Win. Despite being a heel for much of his career, he got over in and outside the ring. Another one of his famous slogans was "I Lie! I Cheat! I Steal!," which was used in one of his entrance themes. He partly uses this phrase in his autobiography Cheating Death, Stealing Life.

Throughout his career, Guerrero encountered various substance abuse problems outside of wrestling, including alcoholism and an addiction to painkillers. His problems outside of the ring were sometimes integrated into his angles. Notwithstanding these issues, he won numerous titles during his career.

His 3 brothers Chavo Guerrero, Hector Guerrero, and Mando Guerrero have all followed in their father's footsteps and became professional wrestlers. Guerrero's nephew, Chavo Guerrero, Jr. also became a wrestler, while his uncle Enrique Llanes and cousin Javier Llanes wrestled in Mexico. As a boy, Guerrero's father allowed him and Chavo Jr. to wrestle one another during intermissions in the wrestling promotions that Gory held.
