"Souviens-toi du jour" (English: "Remember the Day") is a 1999 song recorded by French singer-songwriter Mylène Farmer. It was the third single from her fifth studio album Innamoramento and was released on 2 September 1999. Inspired by Primo Levi's book If This Is a Man, the song deals with the theme of the Holocaust. The song is perhaps best remembered for its controversial music video, which was generally viewed as disrespectful towards its own subject matter.
