John Patrick Douglas Balfour, 3rd Baron Kinross (1904–1976) was a Scottish historian and writer noted for his biography of Mustafa Kemal Atatürk and other works on Islamic history.

He studied at the University of Oxford.
In 1938, he married Angela Mary Culme-Seymour, daughter of George Culme-Seymour and Janet (née Orr-Ewing) and former wife of the artist John Spencer-Churchill. They were divorced in 1942, whereupon Angela married the Comte de Chatellus. She was the model for "the bolter" in Nancy Mitford's novel The Pursuit of Love.
