John Francis Arundell, 16th Baron Arundell of Wardour JP TD (18 June 1907 – 25 September 1944) was a British soldier and member of the House of Lords.

Arundell was the only son of Gerald Arthur Arundell, 15th Baron Arundell of Wardour, by his marriage to Ivy Florence Mary Segrave, daughter of Captain W. F. Segrave. He was educated at Stonyhurst College and New College, Oxford, where he graduated BA. After Oxford, he became a member of the London Stock Exchange, and succeeded to the barony and a seat in the House of Lords on the death of his father in 1939.

Arundell served in the Territorial Army, rising to the rank of captain in the 2nd Battalion the Wiltshire Regiment. He was part of the British Expeditionary Force and in 1940, during the Battle of France, was taken prisoner-of-war by the Germans. He escaped, but was recaptured and was transferred to Oflag IV-C at Colditz Castle. There he had a habit of exercising in the snow and, perhaps as a result, contracted tuberculosis. In accordance with the Geneva Conventions, he was repatriated and died in hospital in Chester. He was buried in the Chapel of New Wardour Castle. He was unmarried, and the barony became extinct upon his death.
