James Edward William Theobald Butler, 3rd Marquess of Ormonde, KP, PC (Ire) (5 October 1844 – 26 October 1919), styled Earl of Ossory until 1854, was an Irish nobleman and member of the Butler dynasty.

The 3rd Marquess also alleged in his letter to Prime Minister Disraeli that his father, John Butler, 2nd Marquess of Ormonde had resolved not to pursue the restoration of the Dukedom of Ormonde unless another peer was also elevated to a Dukedom during his lifetime.

Disraeli responded to the 3rd Marquess' letter on 27 October 1868, and expressed his sympathy with Lord Ormonde's desire to restore "the title of an illustrious ancestor".

[1][11] Upon his death, the family titles passed to his brother Lord Arthur Butler due to his lack of a male heir.

[5] Lord Ormonde's total estate (including entailed property) was valued at approximately £450,000.
