"The Wild Swans at Coole" is a lyric poem by the Irish poet William Butler Yeats (1865–1939).

It was written during a period when Yeats was staying with his friend Lady Gregory at her home at Coole Park, and the assembled collection was dedicated to her son, Major Robert Gregory (1881–1918), a British airman killed during a friendly fire incident in the First World War.

The nineteenth autumn has come upon me Since I first made my count; I saw, before I had well finished, All suddenly mount And scatter wheeling in great broken rings Upon their clamorous wings.

All's changed since I, hearing at twilight, The first time on this shore, The bell-beat of their wings above my head, Trod with a lighter tread.

But now they drift on the still water, Mysterious, beautiful; Among what rushes will they build, By what lake's edge or pool Delight men's eyes when I awake some day To find they have flown away?
