Eric Ryder Hesjedal (; born December 9, 1980) is a Canadian retired professional racing cyclist who competed in mountain biking and road racing between 1998 and 2016. Hesjedal won a silver medal at the 1998 Junior, 2001 Under-23, and Elite world championship in mountain biking. He turned professional with U.S. Postal Service in 2004 after several years with the Rabobank continental team. Having previously finished in fifth place at the 2010 Tour de France, Hesjedal won his first and only Grand Tour at the 2012 Giro d'Italia, the first Grand Tour win by a Canadian. Other major wins include two stages at the Vuelta a España, the first such stage wins by a Canadian.

Danish cyclist Michael Rasmussen asserted in his autobiography that he taught Hesjedal how to take erythropoietin (EPO). Hesjedal later admitted that this doping allegation was "the truth" and that he "chose the wrong path". Hesjedal has not served a ban as a result of his confession to USADA, and has publicly expressed a desire to be honest and transparent. VeloNews reported in 2014 that "The 33-year-old Canadian, however, stopped short of explaining what drugs he took, and when".
