Archibald Henry Macdonald Sinclair, 1st Viscount Thurso, KT CMG PC (22 October 1890 – 15 June 1970), known as Sir Archibald Sinclair, Bt between 1912 and 1952, and often as Archie Sinclair, was a British politician and leader of the Liberal Party.
Born in Chelsea, London, Sinclair was the son of a Scottish father and an American mother. He was the great-great-grandson of Sir John Sinclair, 1st Baronet. In 1912, he succeeded his grandfather, Sir John Sinclair, 3rd Baronet, as fourth Baronet, of Ulbster. Educated at Eton College and the Royal Military College, Sandhurst, he was commissioned into the Life Guards in 1910.
Sinclair served on the Western Front during the First World War and rose to the rank of Major in the Guards Machine Gun Regiment. He served as second-in-command to Winston Churchill, when Churchill commanded the 6th Battalion of the Royal Scots Fusiliers in the Ploegsteert Wood sector of the Western Front in 1916, after Churchill had resigned as First Lord of the Admiralty. They formed a lasting friendship, which would become a significant political alliance in later decades. From 1919 to 1921, he served as Personal Military Secretary to Churchill, when he returned to the Cabinet as Secretary of State for War, then accompanied him to the Colonial Office as Private Secretary.
