Sir John William Kaye KCSI FRS (3 June 1814 – 24 July 1876) was a British military historian, civil servant and army officer. His major works on military history include a three-volume work on The History of the Sepoy War in India. This work was revised later by George Bruce Malleson and published in six volumes in 1890 as Kaye and Malleson's History of the Indian Mutiny.
