The men's individual all-round competition at the 2006 World Artistic Gymnastics Championships was held in Aarhus, Denmark.
Kim Dae-Eun of South Korea withdrew from competition before the final started, but the information did not get in time to Eugen Spiridonov of Germany, who thus missed the final and only 23 gymnasts took part in the competition. The organizers officially apologized for that to the German Gymnastics Union already during the final.
