Cadel Lee Evans AM (/kəˈdɛl/; born 14 February 1977) is an Australian former professional racing cyclist who competed professionally in both mountain biking and road bicycle racing. A four-time Olympian, Evans is one of three non-Europeans – along with Greg LeMond and Egan Bernal – to have won the Tour de France, winning the race in 2011.

Early in his career, he was a champion mountain biker, winning the UCI Mountain Bike World Cup in 1998 and 1999 and placing seventh in the men's cross-country mountain bike race at the 2000 Summer Olympics in Sydney. Evans has competed in four Olympics: in 1996 and 2000 (mountain bike), and in 2008 and 2012 (road bike). Evans turned to full-time road cycling in 2001, and gradually progressed through the ranks. He finished second in the Tour de France in 2007 and 2008. Both of these 2nd place finishes are in the top 10 of the closest Tours in history. He became the first Australian to win the UCI ProTour (2007) and the UCI Road World Championships in 2009.

After finishing outside the top twenty in 2009 and 2010, Evans became the first Australian rider to win the Tour de France in 2011, riding for the BMC Racing Team. He took the race lead on the penultimate day, after completing a 42.5-kilometre (26.4-mile) individual time trial some two-and-a-half minutes quicker than his closest rivals, Andy Schleck and Fränk Schleck. At age 34, he was among the five oldest winners in the race's history. He also made the podium in the 2009 Vuelta a España and the 2013 Giro d'Italia.

Evans retired on 1 February 2015, after completing a race named in his honour.

Cadel Evans was born on 14 February 1977 at the Katherine District Hospital, Katherine, Northern Territory, Australia, to Helen (née Cocks), a bank manager, and Paul Evans, a council foreman. He spent his early childhood in the small Aboriginal community of Barunga, 80 kilometres (50 miles) east of Katherine. At the age of seven, he was hit in the head by a horse, and spent seven days in an induced coma. In 1986, his parents separated and he first moved with his mother to Armidale, New South Wales, and then to the Melbourne suburb of Eltham, Victoria, where his mother still lives. Evans attended Newling Public School in Armidale, and Eltham High School in Melbourne. Skateboarding was one of his teenage interests. His father describes him as a good student, but otherwise just an ordinary kid who would leave his toys around; "Not in [my] wildest dreams" would he imagine that his son would become a top world athlete.

Evans started his international career in 1995 as a Scholarship-holder in the Australian Institute of Sport mountain bike (MTB) Program, under A.I.S. Cycling Program's MTB coach Damian Grundy, and up to 1998 under road coach Heiko Salzwedel. While Evans was at the Australian Institute of Sport, physiological tests showed he possessed a rare combination – an unusually high lung volume and the capacity to absorb more oxygen from each breath than 99.9 per cent of the population. This ability led to him becoming known as 'The Lung'.

Evans won bronze medals at the 1995 Junior world mountain bike championship and Junior world road time trial championship, and silver medals at the 1997 and 1999 under-23 world championships. He won the cross-country overall trophy in the UCI Mountain Bike World Cup in both 1998 and 1999. In 1998 Shayne Bannan^[who?] was the under-23 road cycling coach based in Italy.

Evans competed in two Olympics in mountain bike events: finishing ninth in cross-country at the 1996 Olympics, then finishing seventh at the 2000 Olympics.
