Thoor Ballylee Castle (Irish Túr Bhaile Uí Laí) is a fortified, 15th-century Anglo-Norman tower house built by the septs de Burgo, or Burke, near the town of Gort in County Galway, Ireland. It is also known as Yeats's Tower because it was once owned and inhabited by the poet William Butler Yeats.

It has been described as "the most important public building in Ireland" by late Nobel laureate Seamus Heaney.
