Le Lavandou (pronounced: [lə lavɑ̃du]; Occitan: Lo Lavandor) is a commune in the Var department in the Provence-Alpes-Côte d'Azur region in southeastern France. It derives its name either from the flower lavender (lavanda in Provençal) that is prevalent in the area, or more prosaicly from the local form of the Occitan name for lavoir, lavandor (for lavador, a public place for washing clothes).

The (then) village is where the famous popular song A Nightingale Sang in Berkeley Square was written in the summer of 1939. The words were by Eric Maschwitz and the music by Manning Sherwin, with its title ‘stolen’ from a story by Michael Arlen. The song had its first performance in a local bar, where the melody was played on piano by Manning Sherwin with the help of the resident saxophonist. Maschwitz sang the words while holding a glass of wine, but nobody seemed impressed.

In the spring of 2002, at attempt was made to find the bar where this classic song was first performed with the view to having a blue plaque set up. With the help of the local tourist office, elderly residents were questioned, but it proved impossible to establish the venue.
