Sligo is the county town of County Sligo in northwest Ireland.

The poet W. B. Yeats is associated with Sligo. Much of his writing is descriptive of the area around Sligo town. In particular "The Lake Isle of Innisfree" is a reference to a small, uninhabited island on Lough Gill, which is a lake adjacent to the town. Yeats, who spent much of his youth in Sligo and its environs, died in 1939 and is buried in the graveyard in Drumcliffe, County Sligo.
His epitaph reads: Cast a cold eye, On life, on death, Horseman pass by.
