Tony Craig "TNT" Tucker was a professional Heavyweight boxer during the 1980s and some of the 1990s.

Tucker holds the distinction of twice being the 'mandatory challenger' of a sanctioning body when the reigning champion, refusing to meet Tucker in the ring, saw their championship reign end. In 1987, the International Boxing Federation withdrew its recognition of Michael Spinks as champion when he refused to face Tucker, electing instead to fight famed "Great White Joke" Gerry Cooney. Eight years later, George Foreman relinquished his World Boxing Association crown rather than meet Tucker, saying that there was no public demand for the bout.

Tucker briefly held the IBF's World Heavyweight championship after defeating James "Buster" Douglas for the title in 1987. In his first defense of the title just four months later, Tucker would lose the IBF crown to Mike Tyson via twelve round decision. He would go on to play a minor role in the Heavyweight title picture for the next decade, but never reclaimed any version of the Heavyweight crown.
