"When I Fall in Love" is a popular song, written by Victor Young (music) and Edward Heyman (lyrics). It was introduced in the film One Minute to Zero. Jeri Southern sang on the first recording released in April 1952 with the song's composer, Victor Young, handling the arranging and conducting duties. The song has become a standard, with many artists recording it; the first hit version was sung by Doris Day released in July 1952.

Day's recording was made on June 5, 1952. It was released by Columbia Records as catalog number 39786 and issued with the flip side "Take Me in Your Arms". The song reached number 20 on the Billboard chart.

A 1996 cover by Natalie Cole, a "duet" with her father Nat King Cole by way of vocals from his 1956 cover, won 1996 Grammys for Best Pop Collaboration with Vocals and Best Instrumental Arrangement with Accompanying Vocal(s).

A version was recorded by Nat King Cole on December 28, 1956. It was issued by Capitol Records on an LP album titled Love Is the Thing, catalog number SW824. The song was also used in the 1957 film Istanbul. Cole played in the movie and sang the song. The single was released in the UK in 1957, and reached number 2 on the UK singles chart. This recording was re-released in 1987 and reached number 4. Since 2014, Cole's version of the song has featured in adverts for SSE.
Natalie Cole recorded two different versions of the song: The first, a contemporary R&B/smooth jazz version for her 1987 album, Everlasting then a more traditional version for her 1996 Stardust album, as a virtual duet with her father, Nat King Cole, which included recordings of his vocals from his 1956 version. This version won two awards at the 39th Grammy Awards: Best Pop Collaboration with Vocals and Best Instrumental Arrangement with Accompanying Vocal(s) for arrangers Alan Broadbent and David Foster.
