Óscar Gutiérrez (born December 11, 1974) is an American professional wrestler best known by his ring name Rey Mysterio. He is currently signed to WWE where he performs on the Raw brand. Gutiérrez was trained by his uncle Rey Mysterio and wrestled early on in Mexico where he learned the Lucha Libre high flying style that has been his trademark.
Gutiérrez originally worked for Asistencia Asesoría y Administración (AAA) in Mexico, from 1992 to 1995. He wrestled in Extreme Championship Wrestling (ECW) from 1995 to 1996 and World Championship Wrestling (WCW) from 1996 to 2001, as Rey Misterio, Jr./Rey Mysterio, Jr. but dropped the "Junior" from his name when he began working for WWE in 2002.
Mysterio is known for having a high flying style, which helped kick-start the cruiserweight wrestling revolution in the United States in the late 1990s during his time in WCW. In WCW, Mysterio won the WCW World Cruiserweight Championship five times, the WCW World Tag Team Championship three times, and the WCW Cruiserweight Tag Team Championship once with Billy Kidman as part of the Filthy Animals. In WWE, Mysterio has won the World Heavyweight Championship 2 times, the WWE World Cruiserweight Championship three times (a record eight times overall when added with his WCW reigns), the WWE Tag Team Championship four times (also a record—shared with two others), and the WWE Intercontinental Championship twice, making him the 21st person to win the Triple Crown Championship. Mysterio was also the winner of the 2006 Royal Rumble.

Following his Cruiserweight Championship reign, Mysterio challenged Ultimate Dragon for the J-Crown Championship, but was unsuccessful in his title match at World War 3 in November.
In early 1997, he feuded with Prince Iaukea over the WCW World Television Championship. Mysterio was defeated in his title match against Iaukea at SuperBrawl VII after Lord Steven Regal attacked him.Mysterio also lost a championship rematch at Uncensored in March.Mysterio soon began a feud with the New World Order (nWo), which culminated when he lost a Mexican Death match to nWo member Konnan at Road Wild in August.

He defeated Guerrero in a Title vs. Mask match at Halloween Havoc to win the Cruiserweight Championship for the second time.On the November 10, 1997 edition of Nitro, he lost the title back to Guerrero.
