Colonel Wellington Henry Stapleton-Cotton, 2nd Viscount Combermere (24 November 1818 – 1 December 1891) was a British soldier and Conservative politician.
Combermere was born at Bedford, Bedfordshire, the son of Field Marshal Stapleton Stapleton-Cotton, 1st Viscount Combermere, and Caroline, daughter of William Greville. He was educated at Audlem Grammar School, Cheshire, and Eton College, then attended Christ Church, Oxford in 1837 before entering the army.
Stapleton-Cotton was commissioned into the 7th Hussars in 1837, and served in Canada, where the regiment took part in suppressing the Papineau Rebellion, before returning to England in 1841, when he exchanged his commission into the 1st Life Guards. He was promoted Captain in 1846, and Major in 1850, holding a staff position as Secretary to the Master General of Ordnance from March to December 1852. He was promoted to Lieutenant-colonel in 1857, and achieved the rank of full Colonel in 1861, retiring from the army in 1866.
In 1847 he was returned to Parliament for Carrickfergus, a seat he held until 1857. In 1865 he succeeded his father in the viscountcy and entered the House of Lords.
In 1844 Lord Combermere married Susan Alice, daughter of Sir George Sitwell, 2nd Baronet (1797-1853). They had two sons and two daughters. She died in August 1869. Lord Combermere survived her by 22 years and died of coronary thrombosis at his London home in St James' Place in December 1891, aged 73, seven weeks after being run over by a horse-drawn carriage. He was buried at Wrenbury, Cheshire. He was succeeded in the viscountcy by his eldest son, Robert.
