Major-General Sir Oliver Stewart Wood Nugent, KCB, DSO (9 November 1860[2] – 31 May 1926) was a British Army officer known for his command of the 36th (Ulster) Division during the First World War and particularly at the Battle of the Somme.

He was the son of Major General St George Nugent and Emily, daughter of the Right Honourable Edward Litton, who was a senior Irish judge and MP for Coleraine at Westminster.

[19] He commanded the battalion for the next four years, during which time, in June 1909, he was promoted to brevet colonel and appointed as a personal aide-de-camp to King George VII, taking over from Major General Hubert Hamilton.

[31][32] In common with several other divisions, Nugent deployed his leading battalions into no man's land fifteen minutes before Zero Hour on the first day of the Battle of the Somme in July 1916.

[34] He commanded the Meerut Division in India from August 1918[31][35] to 1920, and, after giving up his assignment at the time,[36] retired from the army in 1920 to the family estate in Farren Connell, County Cavan,[2] where he died from pneumonia on 31 May 1926.
