The 2007 Tour de Suisse, the 71st edition of the cycle race, took place from June 16 until June 24. As usual, the race began with a short prologue and featured a long individual time trial. Besides, riders also had to face several mountain stages in the Swiss Alps, including the Grimselpass, a 12.1 kilometres long climb with an average gradient of 6.6% and slopes at 10%. The race also visited the neighbouring countries of Liechtenstein and Austria.
The four top finishers of the 2006 edition, Jan Ullrich, Koldo Gil, Jörg Jaksche and Ángel Vicioso did not take part in 2007, as in one way or another they were all affected by the Operación Puerto affair. Koldo Gil was the only one of these riders who was not left without a team, after Ullrich was fired by his T-Mobile Team and Vicioso and Jaksche's team Liberty Seguros–Würth folded.

Due to a hailstorm, race officials once abandoned the stage. The stage was later restarted in Ulrichen and was shortened to 95 kilometers. The hors categorie climb of Nufenenpass was cancelled as well.
