The 2005 Nebelhorn Trophy took place between September 29 and October 2, 2005 at the Eislaufzentrum Oberstdorf. The compulsory dance was the Ravensburger Waltz, the same compulsory dance that was used later that season at the 2006 Winter Olympics. It is an international senior-level figure skating competition organized by the Deutsche Eislauf-Union and held annually in Oberstdorf, Germany. The competition is named after the Nebelhorn, a nearby mountain.
