Maryon Gargiulo is a French singer who represented Monaco in the Eurovision Song Contest 2004 in Istanbul, after a 25-year absence, with the song Notre planète, which failed to qualify past the semi finals, finishing in 20th place.
She was chosen from over 500 competitors to represent Monaco in that year's Eurovision but after failing to qualify some people suggested she suffered from France's decision not to broadcast the semi-final and therefore not vote - the two nations would have a tradition of giving each other high marks. The EBU stated that every country broadcasting the final would also have to broadcast the semi-final, meaning that this problem did not arise for Lise Darly, who would represent the country the following year.
She also appeared in the casting rounds for a French talent show in 2006, but does not seem to have progressed far and has not been heard from since.
