Andreas Klier (born 15 January 1976) is a retired German professional road racing cyclist.

[7][8] In addition to his career in cycling, Klier took up painting after seeing works by Max Beckmann at the Museum of Fine Arts, Boston during a layover on a business trip.

[3][9][10] On 15 August 2013, the United States Anti-Doping Agency (USADA) announced that Klier would be suspended for six months after admitting to doping during the period of 1999 to 2006.

[7][8] Klier released his own statement later that day, which expressed regret at his decision of "chose[ing] the wrong path."

To everyone both in and out of cycling including my family, the fans, the sponsors, the sport I love, my peers, – especially those who made the right choices – I am deeply sorry," he said.
