The Singing Nun is a 1966 American semi-biographical musical drama film about the life of Jeannine Deckers, the nun who recorded the chart-topping song "Dominique". Directed by Henry Koster, in his final film, it starred Debbie Reynolds in the title role, and features Ricardo Montalbán, Greer Garson, Katharine Ross, Chad Everett, and Ed Sullivan as himself.

The film featured nine songs by Deckers (credited as Soeur Sourire), of which five had English verses as translated by Randy Sparks, who also wrote two original songs and a third "inspired" by a Soeur Sourire song.
