Thomas Graham, 1st Baron Lynedoch GCB GCMG (19 October 1748 – 18 December 1843) was a Scottish aristocrat, politician and British Army officer. After his education at Oxford, he inherited a substantial estate in Scotland, married and settled down to a quiet career as a landowning gentleman. However, with the death of his wife, when he was aged 42, he immersed himself in a military (and later political) career, during the French Revolutionary Wars and the Napoleonic Wars.

Taylor described Graham as "tall, square-shouldered, and erect, his limbs sinewy and remarkably strong. His complexion was dark, with full eyebrows, firm-set lips, and an open, benevolent air. His manners and address were frank, simple, and polished".^[1]
