Alexis Argüello, also known by the ring name El Flaco Explosivo (lit. "Skinny the Explosive"), was a Nicaraguan professional boxer and politician. As a boxer he was a three-weight world champion, having held the WBA featherweight title as well as the WBC super featherweight and lightweight titles. He has regularly been cited as one of the greatest fighters of his era, having never lost any of his world titles in the ring, instead relinquishing them each time in pursuit of titles in higher weight classes. After his retirement from boxing, Argüello became active in Nicaraguan politics and in November 2008 he was elected mayor of Managua, the nation's capital city.
Arguello is ranked 20th on The Ring magazine's list of "100 greatest punchers of all time" and was voted by the Associated Press in 1999 as the #1 junior lightweight of the 20th century.
He died 1 July 2009.
