"Un Monde parfait" ("A Perfect World" in English) is a 2005 song recorded by French young artist Ilona Mitrecey.

Based on a traditional Neapolitan song,[1] it was the first single from her debut album Un monde parfait and was released on 28 February 2005.

It was immediately a very big hit in France and Belgium (Wallonia), where it remained for several months atop of the chart, thus becoming one of the biggest-selling singles there.

[2] The French charts specialist Elia Habib explains that this song "mixes an involving sonority resembling Daddy DJ with a text in the spirit of a nursery rhyme".

Through her age, she now appears in Record books, [because she is] the second youngest artist to peak at the top position, behind Jordy (four years old)".

One year later, in July 2006, the single made a short appearance of two weeks on the Dutch Mega Top 100, peaking at number 92.

The song was performed by Alizée & Claire Keim, with additional vocals from Grégoire, Christophe Maé & Pascal Obispo.
