Jeffrey "Jeff" Nero Hardy(born August 31, 1977) is an American professional wrestler, currently signed to Total Nonstop Action Wrestling (TNA). He is best known for his time in the World Wrestling Federation/Entertainment (WWE). Before gaining prominence in WWE, Hardy performed for the Organization of Modern Extreme Grappling Arts (OMEGA), a promotion he ran with his brother Matt. After being signed by WWE, the brothers worked as jobbers, before gaining notoriety in the tag team division, partly due to their participation in Tables, Ladders, and Chairs matches. With the addition of Lita, the team became known as Team Xtreme and continued to rise in popularity. As a tag team wrestler, Hardy is a six-time World Tag Team Champion and a one-time WCW Tag Team Champion. Hardy has also experienced success as a singles wrestler and is a three-time world champion, having held the WWE Championship once and World Heavyweight Championship twice, a four-time Intercontinental Champion, and has held the Light Heavyweight, and European Championships once each. He is also a former Hardcore Champion, having held the championship on three occasions. He received his first major main event push towards the end of 2007, including challenging for the WWE Championship at the Royal Rumble in 2008, and eventually won the WWE Championship at the Armageddon pay-per-view in December 2008. Moreover, Hardy is involved in motocross, music, painting, and other artistic endeavors.He is currently a member of the band Peroxwhy?gen.

Hardy cites Sting, The Ultimate Warrior, and Shawn Michaels as his childhood inspirations to wrestle. Hardy had been on World Wrestling Federation (WWF) television as a jobber a wrestler who consistently loses to make his opponents look stronger as early as age sixteen. His first WWF match was against Razor Ramon on May 24, 1994. The next day he wrestled against The 1-2-3 Kid, and the match aired on the June 25 episode of Superstars. He occasionally wrestled as a jobber as late as 1997 before beginning his first major run in 1998. Hardy, along with his brother Matt and friends, started their own federation, the Trampoline Wrestling Federation (TWF) and mimicked the moves they saw on television. Later on, the TWF went under several different names, eventually being integrated into a county fair in North Carolina. The brothers and their friends then began to work for other independent companies. They drove all over the East Coast of the United States, working for companies such as ACW and other small promotions. Before arriving in the WWF, Matt formed his own wrestling promotion, the Organization of Modern Extreme Grappling Arts (OMEGA) with Thomas Simpson. The promotion was a more successful version of the original TWF and included talent such as both Hardy brothers, Shannon Moore, Gregory Helms, Joey Matthews, among others. In OMEGA, each of the brothers portrayed several different characters; Hardy portrayed such characters as Willow the Wisp, Iceman, Mean Jimmy Jack Tomkins, and The Masked Mountain. While there, Hardy held the New Frontier Championship as a singles competitor and the Tag Team Championship with Matt. The promotion folded in April 1998 when they signed contracts with the WWF.

The Hardy brothers eventually caught the eyes of the World Wrestling Federation (WWF). After being signed to a contract in 1998, they were trained by Dory Funk, Jr. in his Funkin' Dojo with other notable wrestlers such as Kurt Angle, Christian, Test, and A-Train. When the team was finally brought up to WWF television, after months of 'jobbing' and live events, they formed the acrobatic tag team called the Hardy Boyz.While feuding with The Brood in mid-1999, they added Michael Hayes as their manager. On July 5, they won their first WWF Tag Team Championship by defeating the Acolytes, but lost it back to them a month later. After the dissolution of the Brood, the Hardys joined forces with Gangrel as The New Brood and feuded with Edge and Christian. This stable did not last long, however, and on October 17, 1999 at No Mercy, the Hardy Boyz won the managerial services of Terri Runnels in the finals of the Terri Invitational Tournament in the WWF's first ever tag team ladder match against Edge and Christian. In 2000, the Hardy Boyz found a new manager in their real-life friend Lita.Together, the three became known as "Team Xtreme". They continued their feud with Edge and Christian throughout 2000, defeating them for the WWF Tag Team Championship on two occasions.At SummerSlam the Hardy Boyz competed in the first ever Tables, Ladders, and Chairs match (TLC match), for the Tag Team Championship against the Dudley Boyz and Edge and Christian, but were unsuccessful. Hardy gained attention for his high risk stunts in the TLC matches in the year 2000, 2001, and 2002.He made a name for himself as one of the most seemingly reckless and unorthodox WWF performers of his time. In 2001, Hardy received a push as a singles competitor, and he held the WWF Intercontinental (defeating Triple H),Light Heavyweight (defeating Jerry Lynn)and Hardcore Championships (defeating Mike Awesome and Van Dam on two separate occasions). At the end of 2001, the Hardys began a storyline in which they began to fight, which led to Matt demanding a match at Vengeance, with Lita as the special guest referee. After Hardy beat Matt at Vengeance, while Matt's foot was on the ropes, Hardy and Lita began feuding against Matt. In the middle of the feud, however, Hardy faced The Undertaker in a Hardcore Championship match and lost. After the match, the Undertaker was scripted to attack both Hardy and Lita, injuring them.On the next episode of SmackDown!, the Undertaker also attacked Matt, also injuring him, in storyline. The Hardys and Lita were not seen again until the Royal Rumble, because WWE did not have another storyline for their characters. The Hardys later came back as a team, and there was never any mention of their previous storyline split. In early April 2002, the Hardy Boyz began a feud with Brock Lesnar after Lesnar gave Matt an F-5 on the steel entrance ramp, which led to an angered Hardy seeking revenge on Lesnar. At Backlash, Hardy faced-off against Lesnar in his first televised match.Lesnar dominated Hardy and won the match by knockout. Lesnar and the Hardys continued to feud over the next few weeks, with the Hardys coming out victorious only once by disqualification. At Judgment Day, Lesnar gained the upper hand on the Hardy Boyz before tagging his partner, Paul Heyman, in to claim the win for the team. In July 2002, Hardy won his third Hardcore Championship by defeating Bradshaw.

On June 23, 2008, Hardy was drafted from the Raw brand to the SmackDown brand, as a part of the 2008 WWE Draft. Hardy made his SmackDown debut on the July 4 episode, defeating John Morrison. Hardy participated in the WWE Championship Scramble match at Unforgiven and also challenged for the Championship at No Mercy and Cyber Sunday, but failed to win each time.[113] He was originally scheduled to be in the WWE Championship match at Survivor Series, but, in storyline, was found unconscious in his hotel, allowing the returning Edge to replace him in the match and win the title. At Armageddon in December 2008, Hardy defeated the defending champion Edge and Triple H in a triple threat match to capture the WWE Championship, his first world heavyweight championship. In January 2009, Hardy's next storyline led to his involvement in scripted accidents, including a hit-and-run automobile accident and an accident involving his ring entrance pyrotechnics. At the 2009 Royal Rumble, Hardy lost his WWE Championship to Edge after Hardy's brother, Matt, interfered on Edge's behalf and hit Hardy with a steel chair. The buildup to this feud involved Matt implying that he was responsible for all of Hardy's accidents over the past few months, and at WrestleMania XXV, Hardy was defeated by Matt in an Extreme Rules match. In a rematch at Backlash, however, Hardy defeated Matt in an "I Quit" match. At Extreme Rules, Hardy defeated Edge to win the World Heavyweight Championship in a ladder match. Immediately after the match, however, CM Punk cashed in his Money in the Bank briefcase, which gave him a guaranteed world championship match at any time he wanted, and defeated Hardy to win the championship. Hardy received his rematch at The Bash, and won the match via disqualification, with Punk still retaining the title. At Night of Champions, however, Hardy won the championship for the second time, by defeating Punk.

Howewer in 2010, Jeff made his return to TNA attacking Homicide after his cage match.The following day, it was reported that Hardy had signed a new contract with TNA.

(Robert Roode and James Storm) in a tag team match. On the August 19 edition of Impact! the TNA World Heavyweight Championship was vacated and Hardy was entered into an eight man tournament for the title, defeating Rob Terry in his first round match.At the semifinals at No Surrender Hardy first wrestled Kurt Angle to a twenty minute time limit draw, after which Eric Bischoff ordered a five minute extra time. After that and a second five minute extra time also ended in draws, it was ruled that, due to a cut, Angle wouldn't be allowed to continue the match, ending the match in a no contest.After wrestling a draw on the September 16 edition of Impact!, it was announced that both Hardy and Angle would advance to the finals at Bound for Glory, where they will compete with Mr. Anderson in a three–way match.

At Bound for Glory, Hardy turned heel with Hulk Hogan and Eric Bischoff and with their help defeated Angle and Anderson to win the TNA World Heavyweight Championship for the first time. They were then joined by Jeff Jarrett and Abyss, revealing the group that Abyss had been referring to as "they" for several months. On the following edition of Impact! the stable was named Immortal, as it formed an alliance with Ric Flair's Fortune. Meanwhile, Hardy debuted a new dark character, using biblical words as he explained the reasons behind his turn.

He has a tattoo of roots that starts on his head, behind his ear, and finishes at his hand. He also has a few other signature designed tattoos, one of which, a dragon, he hid from his father. It was also the first tattoo he got in 1998. He later got tattoos of the Chinese symbols for "Peace" and "Health", as well as tattoos of fire and a wave. Hardy regards his tattoos as his "artistic impulses". Hardy is very good friends with Shannon Moore, who he has known since around 1987. He is also good friends with Marty Garner and Jason Arhndt. He regards Vanilla Ice as a big influence on him, and he was even nicknamed "Ice" by Scott Hall. Hardy met his girlfriend Beth Britt in 1999, shortly after the Hardy Boyz had won the WWF Tag Team Championship for the first time. Hardy and his brother Matt went to a club in Southern Pines, North Carolina, where Hardy met her. On March 15, 2008, it was reported that Hardy's house had burned to the ground in a fire. Hardy and his girlfriend were not home at the time, but his dog, Jack, was killed in the fire. It is believed that the fire was started by faulty electrical wiring. In October 2008, Hardy was building a new home in the same area, which was expected to be completed by early 2009. In August 2010, Hardy announced that Britt was pregnant with the couple's first child, a daughter, who was born on October 28. Hardy married Britt on March 9, 2011. On September 17, 2008, Hardy was involved in an incident at the Nashville International Airport's Southwest gate.
