Carlos Barredo Llamazales (born 5 June 1981, in Oviedo, Asturias) is a Spanish former road racing cyclist, who competed as a professional between 2004 and 2012. He was issued a suspension for the first two months of the 2011 season in response to a fight with Rui Costa after a 2010 Tour de France stage, with Barredo claiming that Costa had ridden dangerously in the final stages of the race, but later apologising for his actions.
