The Hardy Boyz was a professional wrestling tag team in World Wrestling Entertainment that consisted of brothers Jeff and Matt Hardy. Originally the brothers competed as teenagers in the then-WWF as jobbers, both in singles and tag team competition. They started their run as a popular tag team in a surprising win over Kaientai (Taka Michinoku and Shoichi Funaki) on WWF Sunday Night Heat. They are generally considered to be one of the best tag teams in WWE history.

Before Team Xtreme

Soon after their Sunday Night Heat win, they built up a fan following through their high-flying tag team tactics. They started to become serious contenders for the Tag Team Titles after they became managed by Michael "P.S." Hayes , formerly a member of the successful tag team the Fabulous Freebirds. They would eventually dump Hayes as their manager and were briefly associated with Gangrel as part of The New Brood. After winning a series of matches with Edge and Christian, dubbed the "Terri Invitational Tournament", they won the services of Terri Runnels as their manager. Through all this they had a successful run for the tag team titles, but they would gain the most notoriety as a tag team with Lita.

Team Xtreme

Together with Lita, Matt and Jeff Hardy comprised the trio dubbed "Team Xtreme", their name serving as a reflection of their "extreme" high-flying moves. During the time they were in WWE together, they were one of the most popular tag teams, primarily because of their TLC (Tables, Ladders and Chairs) matches with Edge and Christian as well as the Dudley Boyz. The high-flying tactics of the young Hardy brothers and Lita would make them one of the most popular tag teams in the WWF at that time, particularly among female fans. The team would eventually split up however in favor of both Matt and Jeff pursuing singles careers. Matt Hardy would find some measure of success on Smackdown! as Matt Hardy V1, while Jeff competed as a singles wrestler on WWE RAW.

Matt remained in WWE until 2005, while Jeff is in Total Nonstop Action.
