Floyd Landis (born October 14, 1975) is an American retired cyclist who after initially being awarded victory in the 2006 Tour de France was stripped of his title for a doping offense. He was an all-around rider, with special skills in climbing and time-trialing, and is also known to be a very fast descender. Landis turned professional in 1999 with the Mercury Cycling Team. He joined the US Postal Service team in 2002, and moved to the Phonak Hearing Systems team in 2005. In January 2010, a French judge issued a national arrest warrant for Landis on computer hacking charges related to the 2006 doping allegations.
In 2006, Landis won the first edition of the Amgen Tour of California, before going on to finish first in the 2006 Tour de France. He was stripped of his Tour de France victory and fired from the Phonak team after a drug-control test demonstrated the presence of a skewed testosterone/epitestosterone ratio during stage 17.
Until 2010, Landis maintained his innocence, and mounted a vigorous defense. Although Landis's legal team documented inconsistencies in the handling and evaluation of his urine samples, the disqualification was upheld.
