World Idol (Germany: SuperStar Weltweit, Arab World: SuperStar El Alaam) is a one-off international version of the singing competition television show Pop Idol, featuring winners of the various national Idol shows around the world competing against each other.

The performance show was broadcast on Christmas Day 2003, with the results show aired on New Year's Day 2004. It was produced in the United Kingdom at Fountain Studios in London, using the set from the recently completed second series of Pop Idol. After presenting the competitors, viewers from the 11 participating countries were allowed to vote by telephone, but not for the participant from their home country.

All participants sang in English except for Diana Karazon, who sang in Arabic.

British presenters Ant & Dec hosted the show on most English speaking countries, while local presenters hosted for their own country in the local language. Additionally, Canada’s CTV Network used Canadian Idol host Ben Mulroney (with the show on Fox, which used Ant and Dec as hosts, was not simulcast with the CTV feed, to prevent Canadians from calling the American toll-free number to vote for their idol, Ryan Malcolm). Victoria Beckham performed her UK No. 3 hit "Let Your Head Go" during the results interval.

The show was broadcast on 11 television broadcasters worldwide.

The points were awarded in a similar fashion as the Eurovision Song Contest, i.e. each country awarded a number of points from 1 to 10 to each other country, using each number once. The results were:

Each country appointed a spokesperson (or a pair of spokespersons) to announce their respective country's points.

Each country's Idol automatically gained the maximum 12 points. Therefore, the most points an Idol could gain from another country was 10.
