Alberto Contador Velasco (Spanish pronunciation: [alˈβerto kontaˈðor βeˈlasko]; born 6 December 1982) is a Spanish professional road bicycle racer, who last rode for UCI ProTeam Team Saxo Bank. He was the winner of the 2007 Tour de France with the Discovery Channel team. With the Astana team he has won the 2008 Giro d'Italia, the 2008 Vuelta a España and the 2009 Tour de France. He initially also won the 2010 Tour de France with this team, and the 2011 Giro d'Italia with team Saxo Bank-SunGard, only to be stripped from these titles later having been found guilty of a doping offence. He is the fifth racer in history, and the first Spaniard, to win all three Grand Tours of road cycling.

Contador is widely considered to be the best climbing specialist and stage racer in the world. Notable summit stage finishes on which he has victories include the Alto de El Angliru in the Vuelta, the Plateau de Beille in the Tour and Mount Etna in the Giro. After being widely expected to lose his tenuous lead in the 2007 Tour de France in that race's final individual time trial, Contador has become a more accomplished time trialist, with several victories in the discipline. He has earned a reputation as an all-rounder, a cyclist who excels in all aspects of stage racing which are needed for high places in the general classification.
