Francis Jammes was a French and European poet. He spent most of his life in his native region of Béarn and the Basque Country and his poems are known for their lyricism and for singing the pleasures of a humble country life (donkeys, maidens). His later poetry remained lyrical, but also included a strong religious element brought on by his (re)conversion to Catholicism in 1905.

Jammes was a mediocre student and failed his baccalauréat with a zero for French. His first poems began to be read in Parisian literary circles around 1895, and were appreciated for a fresh tone breaking away from symbolism.

In 1896 Jammes travelled to Algeria with André Gide. He fraternised with other writers, including Stéphane Mallarmé and Henri de Régnier. His most famous collection of poems — De l'angélus de l'aube à l'angélus du soir ("From morning Angelus to evening Angelus") — appeared in 1897 in the Mercure de France; Le Deuil des Primevères ("The Mourning of Primulas") (1901) was also well received. Working up to that point as a notary's clerk, Jammes was then able to make a living from his writing. In 1905, influenced by the poet Paul Claudel to whom he became close, he converted to a practicing Catholicism. His poetry became more austere and sometimes dogmatic.

In the eyes of Parisian literary circles, Francis Jammes was generally considered a solitary provincial who chose to live a life of retreat in his mountainous Pyrenees, and his poems never became entirely fashionable. The author sought nomination to the Académie française several times, but was never elected.

Jammes was the original author of Georges Brassens's song La Prière ("The Prayer"). The lyrics were taken from the poem Les Mystères douloureux ("The Agonies of Christ") published in the collection L'Église habillée de feuilles ("The Church Clothed in Leaves") (1906); Brassens changed some of the words to make the text more rhythmic.

Jammes was known to have an ardent passion for field sports, especially game hunting. He was known to have also been a believer in the conservation of endangered species.

Thirteen poems from his cycle Tristesses ("Sorrows"), were set to music by composer Lili Boulanger in 1914 under the title Clairières dans le ciel ("Clearings in the Sky") a title Jammes had given to an assorted collection of poetry of which Tristesses was a part. The whole cycle was composed for soprano, flute and piano by Michel Bosc.
