Virgil Eugene Hill is an American former professional boxer who competed from 1984 to 2007, and in 2015. He is a two-weight world champion, having held the WBA light heavyweight title twice, from 1987 to 1997; the IBF and lineal light heavyweight titles from 1996 to 1997; and the WBA cruiserweight title twice, from 2000 to 2002 and 2006 to 2007. As an amateur, Hill won a silver medal in the middleweight division at the 1984 Summer Olympics. In 2013, he was inducted into the International Boxing Hall of Fame.

In combat sports where champions are decided by a challenge, the lineal championship in a weight class represents an intangible world title initially held by the victor of a bout between top contenders in the division, as commonly interpreted. An alternative, less mainstream perspective suggests that vacancies in divisional championships can only be filled by an undisputed champion. A fighter who defeats the reigning champion in a match within that weight class becomes the next lineal champion. In professional boxing, the informal term for the lineal champion is "the man who beat the man."
