"A Nightingale Sang in Berkeley Square" is a British romantic popular song written in 1939 and published in 1940, with lyrics by Eric Maschwitz and music by Manning Sherwin.

[1] The song was written in the then-small French fishing village of Le Lavandou—now a favourite resort for British holidaymakers and second-home owners—shortly before the outbreak of the Second World War.

"When the Nightingale Sang in Berkeley Square" is the title of a short story by Michael Arlen, published in 1923 as part of his collection These Charming People.

The song had its first performance in the summer of 1939 in a local bar, where the melody was played on piano by Manning Sherwin with the help of the resident saxophonist.

[2] The verse and the additional lyrics to a second chorus were in the song as written, but are rarely sung in recordings (those of Bobby Darin, Mel Torme, Blossom Dearie, Twiggy, Vera Lynn and Rod Stewart being notable exceptions).

It was notably sung by Elsie Carlisle, an English female singer active both before and during the British dance band era.

Early chart hits of the song in the US were by Glenn Miller, Ray Noble, Guy Lombardo and Sammy Kaye.

The veteran British musician Ian Hunter, former vocalist for Mott the Hoople, regularly performs it in his concerts; and it has appeared on two at least of his live recordings.

[23] On 9 May 2015 Katherine Jenkins sang the song at VE Day 70: A Party to Remember at Horse Guards Parade in London.
