"My Number One" is the 2005 winning song of the 50th Eurovision Song Contest. It was performed in English by Helena Paparizou and the first Greek win in the Eurovision. The song was written by Christos Dantis, with lyrics by him and Natalia Germanou. It also contains music from a traditional greek instrument, the lyra.

As Greece had finished the 2004 Contest in third place, the song was pre-qualified for the final in 2005. Thus, it was performed nineteenth on the night (following Croatia's Boris Novković and Lado with "Vukovi Umiru Sami" and preceding Russia's Natalia Podolskaya with "Nobody Hurt No One"). At the close of voting, it had received 230 points, finishing at the head of a 24-strong field.

The song is an up-tempo love song, with Helena telling her lover that he is "my number one" and "the only treasure I'll ever have". Interestingly, BBC commentator Terry Wogan quoted alternative lyrics prior to Paparizou's performance ("You're the most impressive person I've discovered").
The performance is best-remembered for Helena sitting on a human pyramid of her backing dancers and playing an imaginary lyra.

At the Congratulations special in late 2005, the song was named as one of the five greatest Contest entries of all time.

After the Eurovision Victory a video was filmed and released in several countries throughout Europe. It went to Number one in both Sweden and Greece for 4 weeks in both countries and became gold.

After the release of "My Number One" a Swedish album followed which contained "My Number One" and in Greece Elena re-released her number one album Protereotita featuring "My Number One" and the other songs in the running for Eurovision preselection.

In early 2006 it was announced that "My Number One" and "Mambo!" would be remixed and released in the USA and Canada by Moda Records. Billboard has confirmed the release date for "My Number One" to be 22nd August. The mixes have been released in US i-tunes. "My Number One" is also released in the US territories.

The music video of "My Number One" is now showing in America with another video of the original video re-edited with the Josh Harris Remix of the song.
