France in the Eurovision Song Contest 2018

France was represented at the Eurovision Song Contest 2018 with the song "Mercy" written by Émilie Satt and Jean-Karl Lucas, and performed by themselves as Madame Monsieur. The French entry for the 2018 contest in Lisbon, Portugal was selected through the national selection Destination Eurovision, organised by the French broadcaster France Télévisions in collaboration with the television channel France 2. The selection consisted of two semi-finals and a final. Madame Monsieur became the winner, placing third with the international juries but winning a landslide share of the vote from the French public, amassing enough points to win the competition. This was the first time France used a national final since 2014.

As a member of the "Big Five", France automatically qualified to compete in the final of the Eurovision Song Contest.
