Lourmarin (French pronunciation: [luʁmaʁɛ̃]; Occitan: Lormarin) is a commune in the Vaucluse department in the Provence-Alpes-Côte d'Azur region in southeastern France.

Its mayor between 2001 and 2017 was Blaise Diagne, grandson of the like-named first Black African deputy and member of a French government.

Another famous writer, British expatriate Peter Mayle lived in Vaugines, near Lourmarin, until his death in 2018.

One of his books, A Year in Provence, giving the chronicle of a British expatriate who settled in the village of Ménerbes, was made into a TV series and a film.

As a result, in recent decades Luberon and its towns and villages like Lourmarin and Ménerbes, which probably were the lesser known parts of Provence, even in France, became better known in the English-speaking world.
