Christopher Keith Irvine (born November 9, 1970), better known by the ring name Chris Jericho is an American-Canadian professional wrestler and rock musician. He is currently signed to All Elite Wrestling (AEW), where he was the leader of the Jericho Appreciation Society and the Inner Circle stables. Noted for his over-the-top rock star persona, in-ring technical wrestling prowess, and his ability to reinvent his character throughout the course of his career, Jericho has been named by journalists and industry colleagues as one of the greatest professional wrestlers of all time. During the 1990s, Jericho performed for American organizations Extreme Championship Wrestling (ECW) and World Championship Wrestling (WCW), as well as for promotions in countries such as Canada, Japan, and Mexico. At the end of 1999, he made his debut in the World Wrestling Federation (WWF). In 2001, he became the first Undisputed WWF Champion, and thus the final holder of the WCW World Heavyweight Championship (then referred to as the World Championship), having won and unified the WWF and World titles by defeating Stone Cold Steve Austin and The Rock on the same night. Jericho headlined multiple pay-per-view (PPV) events during his time with the WWF/WWE, including WrestleMania X8 and the inaugural TLC and the Elimination Chamber matches and the shows itself. He was inducted into the Wrestling Observer Newsletter Hall of Fame in 2010. Within the WWF/WWE, Jericho is a six-time world champion, having won the Undisputed WWF Championship once, the WCW/World Championship twice and the World Heavyweight Championship three times. He has also held the WWE Intercontinental Championship a record nine times and was the ninth Triple Crown Champion, as well as the fourth Grand Slam Champion in history. In addition, he was the 2008 Superstar of the Year Slammy Award winner and (along with Big Show as Jeri-Show) won the 2009 Tag Team of the Year Slammy Award—making him the only winner of both Superstar and Tag Team of the Year.
