"Dominique" is a 1963 French language popular song, written and performed by Belgian singer Jeannine Deckers, better known as Sœur Sourire ("Sister Smile" in French) or The Singing Nun. The song is about Saint Dominic, a Spanish-born priest and founder of the Dominican Order, of which she was a member (as Sister Luc-Gabrielle). The English-version lyrics of the song were written by Noël Regney. In addition to French and English, Deckers recorded versions in Dutch, German, Hebrew, Japanese, Korean, and Portuguese. It was a top selling record in 11 countries in late 1963 and early 1964.
