Monaco in the Eurovision Song Contest 2005

Monaco participated in the Eurovision Song Contest 2005 with the song "Tout de moi" written by Philippe Bosco and Didier Fabre. The song was performed by Lise Darly, who was internally selected by the Monégasque broadcaster Télé Monte-Carlo (TMC) to represent Monaco in the 2005 contest in Kyiv, Ukraine. The selection of Lise Darly and "Tout de moi" as the Monégasque entry was announced on 12 January 2005, while the song was presented on 18 March 2005.

Monaco competed in the semi-final of the Eurovision Song Contest which took place on 19 May 2005. Performing during the show in position 6, "Tout de moi" was not announced among the top 10 entries of the semi-final and therefore did not qualify to compete in the final. It was later revealed that Monaco placed twenty-fourth out of the 25 participating countries in the semi-final with 22 points.

Background
Prior to the 2005 contest, Monaco has participated in the Eurovision Song Contest twenty-two times since its first entry in. The nation has won the contest once (in with the song "Un banc, un arbre, une rue" performed by Séverine), making them the only microstate to have won the contest to date. Monaco has also placed last on two occasions: in 1959 and which also received nul points. Between and, Monaco did not participate in the contest for financial reasons and lack of interest, while the nation returned in  with the song "Notre planète" performed by Maryon but failed to qualify to the final from the semi-final.

The Monégasque national broadcaster, Télé Monte-Carlo (TMC), broadcasts the event within Monaco and organises the selection process for the nation's entry. TMC confirmed that Monaco would participate in the 2005 Eurovision Song Contest on 6 October 2004. All Monégasque entries had been selected by TMC through an internal selection, a method that was continued for their 2005 participation.

Internal selection
The Monégasque entry for the 2005 Eurovision Song Contest was selected internally by TMC. The French broadcaster France 3 as well as Prince Albert II and Princess Stéphanie of Monaco were also involved in the selection process. On 12 January 2005, it was announced that Lise Darly would represent Monaco at the 2005 contest with the song "Tout de moi". Darly, whose real name is Elise Granier, had previously attempted to represent Monaco at Eurovision Song Contest in 2004 placing second at the artist selection, and was selected from a shortlist of twelve female performers considered by TMC.

"Tout de moi" was written by Philippe Bosco and Didier Fabre, and was selected from several proposals received by record companies. Bosco had also previously written the Monégasque Eurovision song in 2004. In early February 2005, Darly recorded "Tout de moi" in Monaco at the Auditorium Rainier III together with the Monte-Carlo Philharmonic Orchestra, conducted by Jean-Louis Dedieu. The song was presented to the public online via the Eurovision news website ESCToday on 18 March 2005.

At Eurovision
According to Eurovision rules, all nations with the exceptions of the host country, the "Big Four" (France, Germany, Spain and the United Kingdom), and the ten highest placed finishers in the 2004 contest are required to qualify from the semi-final on 19 May 2005 in order to compete for the final on 21 May 2005; the top ten countries from the semi-final progress to the final. On 22 March 2005, an allocation draw was held which determined the running order for the semi-final and Monaco was set to perform in position 6, following the entry from Latvia and before the entry from Israel. At the end of the show, Monaco was not announced among the top 10 entries in the semi-final and therefore failed to qualify to compete in the final. It was later revealed that Monaco placed twenty-fourth in the semi-final, receiving a total of 22 points.

Both the semi-final and the final were broadcast in Monaco on TMC with commentary by Bernard Montiel and Genie Godula. The Monégasque spokesperson, who announced the results of the Monégasque jury during the final, was Anne Allegrini.
