Hardy was born in Cameron, North Carolina, the son of Gilbert and Ruby Moore Hardy. He is the older brother of Jeff Hardy. Their mother died of brain cancer in 1986. Hardy played baseball as a child and throughout high school, but had stopped by his senior year.

At the beginning of 2002, it seemed Team Xtreme had patched things up. After the brand extension, however, Hardy was relegated to Heat while Jeff wrestled on the main show, Raw. On the August 12 episode of Raw, Hardy turned against Jeff during Jeff's match against Rob Van Dam, because Hardy was frustrated at not receiving a match against Van Dam for the number one contendership for the Intercontinental Championship. A short time later, Hardy joined the SmackDown! roster, and began dubbing himself "Matt Hardy: Version 1", complete with a "version 1" hand signal. Hardy defeated The Undertaker on the September 12 and October 3 episodes of the show, due to interference from Brock Lesnar.  Along with his MF'er (Mattitude Follower) Shannon Moore in his corner, 2003 began with Hardy frantically trying to lose weight to get under the 215 lb (98 kg) weight limit to compete for the Cruiserweight Championship. After just barely making weight, Hardy defeated Billy Kidman at No Way Out to win the Cruiserweight title. At WrestleMania XIX, he successfully defended it against Rey Mysterio. Hardy lost the Cruiserweight Championship to Mysterio in the main event of the June 5 edition of SmackDown - the first and only time a Cruiserweight Championship match main evented a show.  After dropping the Cruiserweight Championship, Hardy briefly feuded with Eddie Guerrero, but was unsuccessful in capturing Guerrero's United States Championship or Tag Team Championship. The Mattitude faction then expanded to include Crash Holly as Moore's "Moore-on" (apprentice). He later disbanded the group in November and returned to Raw in order to be able to travel and work with his then girlfriend Lita, who just returned from an injury. On his first night back, he turned on Lita in storyline after teasing a proposal to her. He defeated Christian, who was vying for Lita's affections, on the following edition of Raw.  In April 2004, Hardy saved Lita from getting attacked by Kane. Hardy defeated Kane at Vengeance, but lost a match against Kane at SummerSlam. On the August 23 episode of Raw, Hardy was chokeslamed off the stage by Kane. Hardy then spent almost a year off from wrestling due to a severe knee injury.
