Colonel John Jestyn Llewellin, 1st Baron Llewellin GBE MC TD PC (6 February 1893 – 24 January 1957) was a British army officer, Conservative Party politician and minister in Winston Churchill's war government.

Llewellin was the son of William Llewellin, of Upton House, Dorset, and Frances Mary, daughter of L. D. Wigan. He was educated at Eton.

Llewellin was commissioned into the Royal Garrison Artillery in 1914 and reached the rank of Major during the First World War, winning the Military Cross in 1917. He remained in the Territorial Army after the war and was promoted to Lieutenant-Colonel commanding the Dorset Heavy Brigade in 1932. He was promoted Colonel in 1936 and retired in 1938. He was appointed an Officer of the Order of the British Empire (OBE) in 1926, promoted to a Commander (CBE) in 1939, and then was made a Knight Grand Cross (GBE) in 1953.

Llewellin was elected Member of Parliament (MP) for Uxbridge in Middlesex in 1929. He held a number of ministerial posts in the Coalition government, eventually serving as President of the Board of Trade for two weeks in 1942. He subsequently became Minister of Aircraft Production in which capacity he served on the Combined Policy Committee set up by the British and United States governments under the Quebec Agreement of 1943 to oversee the construction of the atomic bomb.
