Gavin George Hamilton, 2nd Baron Hamilton of Dalzell, KT, CVO, MC (29 June 1872 – 23 June 1952), was a Scottish Liberal politician.
Hamilton was the eldest surviving son of John Hamilton, 1st Baron Hamilton of Dalzell, and his wife Lady Emily Eleanor, daughter of Alexander Leslie-Melville, 10th Earl of Leven. He was commissioned a second lieutenant in the Scots Guards on 30 March 1892, and promoted to lieutenant on 20 March 1897, but resigned and was appointed to the Reserve in January 1900 with the rank of captain. He volunteered for service in the Second Boer War in South Africa the following month, and was appointed a lieutenant in the 4th Battalion Imperial Yeomanry on 17 February 1900. Attached to the 28th (Bedfordshire) company, he left Albert Docks in the SS Kent in early February 1900, and arrived at South Africa the following month.
He succeeded his father in the barony in 1900 and took his seat on the Liberal benches in the House of Lords. From 1905 to 1911 he served under Sir Henry Campbell-Bannerman and later H. H. Asquith as a Lord-in-Waiting (government whip in the House of Lords).
He was appointed a Deputy Lieutenant of Lanarkshire in September 1901, and served as Lord-Lieutenant of Lanarkshire between 1938 and 1952. In 1909 he was made a Knight of the Thistle.
Lord Hamilton of Dalzell married Sybil Mary, daughter of Lieutenant-General Sir Frederick Marshall, in 1912. She died in 1933. Hamilton survived her by nineteen years and died in June 1952, aged 79. He was succeeded in the barony by his nephew John (1911-1990).
