The 2003 Nebelhorn Trophy took place between 3 and 6 September 2003 at the Bundesleistungszentrum Oberstdorf.

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.

Skaters were entered by their respective national federations, rather than receiving individual invitations as in the Grand Prix of Figure Skating, and competed in four disciplines: men's singles, ladies' singles, pair skating, and ice dance.

The Fritz-Geiger-Memorial Trophy was presented to Canada, the country with the highest placements across all disciplines.
