Paulino Uzcudun Eizmendi (3 May 1899 – 5 July 1985) was a Basque Spanish heavyweight boxer, who is considered to be the greatest heavyweight from Spain. Uzkudun is the Basque spelling of his last name. He was the youngest of nine siblings. In his youth, he became an aizkolari or traditional competitive Basque wood chopper. Uzcudun, known as Paulino in the United States, was the European heavyweight champion, and he fought heavyweight champions Joe Louis, Max Baer, Max Schmeling (three times) and Primo Carnera (twice) during his career. He had a powerful left hook, and fought the toughest heavyweights of his time. He had only one opportunity at the world's heavyweight championship, but was defeated in a fifteen-round fight by Primo Carnera of Italy on October 22, 1933.
Uzcudun also "retired" the famed Harry Wills, when he stopped him in four rounds on July 13, 1927.
