General Sir Thomas Montagu Steele (11 May 1820, Guilsborough, Northamptonshire – 25 February 1890 Frimley Park, Farnborough) was a British army officer.
As the eldest son of Major-General Thomas Steele and Lady Elizabeth Montagu, second daughter of the fifth duke of Manchester, he attended Royal Military College, Sandhurst, before being commissioned as an ensign in the 64th foot in January 1838. Exchanging into the Coldstream Guards on 20 July that year, he served as aide-de-camp to the governor of Madras (1842–48) rose to lieutenant in 1844, captain later that year and brevet lieutenant-colonel in 1851. Promoted to brevet colonel in 1854, he served as Lord Raglan and his successor's military secretary (1854–1855, apart from 5 July to 6 August 1855 when Steele served as assistant adjutant general – in that role he served at the battles of the Alma, Balaklava, Inkerman and Sevastopol, being mentioned in dispatches).[1]

He married his first wife Isabel Fitzgerald in 1856 and, on her death 2 years later, he remarried in 1865 to the American Rosalie Malvina McCarty of New York. Steele was promoted to the substantive rank of major in 1860 and the substantive rank of lieutenant colonel in 1862 before retiring to half pay on 24 November 1863.
