Colonel James Archibald Stuart, later Stuart-Wortley-Mackenzie (19 September 1747 – 1 March 1818), British politician and soldier, was the second son of John Stuart, 3rd Earl of Bute and his wife Mary Stuart, Countess of Bute.

On 8 June 1767 he married Margaret Cunynghame, daughter of Sir David Cunynghame, 3rd Baronet, and they had five children:[citation needed]

A colonel in the Bedfordshire militia, he raised the 92nd Regiment of Foot in 1779, and was appointed lieutenant-colonel commanding. He brought it to the West Indies in 1780, and suffered severely in health. He returned home in 1783 and the regiment was disbanded, following the Treaty of Paris.

Upon the death of his mother, in 1794, he inherited the properties of the Wortley family, and assumed that surname on 17 January 1795. In 1800, he added the additional surname of Mackenzie, having succeeded to the estates of his uncle James Stuart Mackenzie.[1]
