Thomas Moore (Dublin, 28 May 1779 – Sloperton Cottage, Bromham, Wiltshire, 25 February 1852) was an Irish writer, poet, and lyricist celebrated for his Irish Melodies. Their setting of English-language verse to old Irish tunes marked the transition in popular Irish culture from Irish to English. Politically, Moore was recognised in England as a press, or "squib", writer for the aristocratic Whigs; in Ireland he was accounted a Catholic patriot.
Married to a Protestant actress and hailed as "Anacreon Moore" after the classical Greek composer of drinking songs and erotic verse, Moore did not profess religious piety. Yet in the controversies that surrounded Catholic Emancipation, Moore was seen to defend the tradition of the Church in Ireland against both evangelising Protestants and uncompromising lay Catholics. Longer prose works reveal more radical sympathies. The Life and Death of Lord Edward Fitzgerald depicts the United Irish leader as a martyr in the cause of democratic reform. Complementing Maria Edgeworth's Castle Rackrent, Memoirs of Captain Rock is a saga, not of Anglo-Irish landowners, but of their exhausted tenants driven to the semi-insurrection of "Whiteboyism".
Today Moore is remembered almost alone either for his Irish Melodies (typically "The Minstrel Boy" and "The Last Rose of Summer") or, less generously, for the role he is thought to have played in the loss of the memoirs of his friend Lord Byron.

War Song
Remember the glories of Brien the brave,
Though the days of the hero are o'er,
Though lost to Mononia and cold to the grave,
He returns to Kinkora no more.
That star of the field, which so often hath pour'd
Its beam on the battle, is set;
But enough of its glory remains on each sword,
To light us to victory yet.
Mononia! when Nature embellish'd the tint
Of thy fields, and thy mountains so fair,
Did she ever intend that a tyrant should print
The footstep of slavery there?
No! Freedom, whose smile we shall never resign,
Go, tell our invaders, the Danes,
That 'tis sweeter to bleed for an age at thy shrine,
Than to sleep but a moment in chains.
Forget not our wounded companions who stoood
In the day of distress by our side;
While the moss of the valley grew red with their blood,
They stirr'd not, but conquer'd and died.
That sun which now blesses our arms with his light,
Saw them fall upon Ossory's plain; --
Oh! let him not blush, when he leaves us to-night,
To find that they fell there in vain.
