Matthew Moore Hardy is an American professional wrestler signed to All Elite Wrestling (AEW) under his "Big Money" Matt moniker, where he is the leader of the Hardy Family Office. He is also known for his time with WWE, Impact Wrestling, and Ring of Honor (ROH).

With his real life brother Jeff, Hardy gained notoriety in WWF's tag team division during the 2000s due to his participation in TLC matches. He is a 14-time world tag team champion, having held the WWE World Tag Team Championship six times, the WWE Raw Tag Team Championship three times, the WWE SmackDown Tag Team Championship, ROH World Tag Team Championship, and WCW Tag Team Championship once each, and the TNA World Tag Team Championships twice. All but two Raw Tag Team Championship reigns came with Jeff as his partner.

Wrestling through four separate decades, Hardy has kept himself relevant partially through a variety of different gimmicks and his use of social media. In 2002, Hardy began a solo career in WWE. His subsequent "Version 1" persona was named Best Gimmick by the Wrestling Observer Newsletter. Hardy's eccentric "Broken" gimmick, which he debuted in 2016 (and which was renamed "Woken" following his subsequent WWE return), garnered praise from wrestling critics and earned him multiple awards, including a second Best Gimmick award. As a singles wrestler, Hardy has won three world championships (one ECW Championship, and two TNA World Heavyweight Championships). All totaled between WWE, TNA/Impact, and ROH, Hardy has held 21 total championships.
