"T'en va pas" (Eng. "Don't Go Away") is a 1986 song recorded by the French artist Elsa Lunghini. Released as a single on 12 October 1986, this song, her debut single, was the soundtrack of the 1986 movie La Femme de ma vie. It was a smash hit in France.

In the movie, Elsa portrayed Jane Birkin's daughter and played the piano in a short scene. Finally, a whole song had been composed by Romano Musumarra, who decided to release it as a single. Musumarra had already worked and helped produce hits for two famous French artists of the 80s—Jeanne Mas ("En Rouge et Noir") and Princess Stephanie of Monaco ("Ouragan").

"T'en va pas" was a huge hit in France, and managed to export itself across Europe with an English recording : "Papa, Please Don't Go". It became well known in Japan because it was used for Jeans' TV commercial there. Also in Japan, Tite Kubo used the song as the image song for the character Orihime Inoue from Bleach. It also was used as the image song for the character Yumisuka Satsuki from Tsukihime. In 2008 the song was used in television commercials for Impulse brand deodorant, in Argentina. The song was available in the French and English languages on the best of Elsa, l'essentiel 1986-1993.

The music video shows images from the movie alterning with Elsa performing the song.

In the mid-2000s, the song was covered in a live version by Priscilla on the TV show Absolument 80 broadcast on M6.
