"Où es-tu, mon amour?" is a French song with music by Emil Stern and lyrics by Henri Lemarchand. Its sheet music also appears under the title "Ou Es-Tu Mon Amour?". The original recording was made in 1946 by Renée Lebas with the orchestra of Guy Luypaerts. Yves Montand recorded it in 1959 with the orchestra of Hubert Rostaing.
Played as a gypsy jazz ballad in the manner of the Django Reinhardt Hot Club, the song is slow, melancholic and romantic. Later versions include those by the Charlie Haden Quartet West (1994), Willie Nelson (1998), Biréli Lagrène (2002), the Angelo Debarre Quartet (2004), Dorado Schmitt, Babik Reinhardt and Christian Escoudé (2007), and the Rosenberg Trio.
