Down by the Salley Gardens (Irish: Gort na Saileán) is a poem by William Butler Yeats published in The Wanderings of Oisin and Other Poems in 1889. Yeats indicated in a note that it was "an attempt to reconstruct an old song from three lines imperfectly remembered by an old peasant woman in the village of Ballisodare, Sligo, who often sings them to herself." The "old song" may have been the ballad "The Rambling Boys of Pleasure". Yeats's original title, "An Old Song Re-Sung", reflected this; it first appeared under its present title when it was reprinted in Poems in 1895. The verse was subsequently set to music by Herbert Hughes to the airThe Maids of the Mourne Shore in 1909. In the 1920s composer Rebecca Clarke (1886-1979) set the text to music. There is also a vocal setting by the poet and composer Ivor Gurney, which was published in 1938; and another by Benjamin Britten published in 1943. The composer John Ireland earlier set the words to an original melody in his cycle "Songs Sacred and Profane', written in 1934.
"Salley" is an anglicisation of the Irish saileach, meaning willow, i.e., a tree of the genus Salix. Willows are known as "salleys", "sallies" or "salley trees" in parts of Ireland.
