Sir Alexander John Arbuthnot KCSI CIE (11 October 1822 – 10 June 1907) was a British official and writer.

Arbuthnot was honoured by the Crown with the titles of Knight Commander of The Most Exalted Order of the Star of India (1873) and Companion of The Most Eminent Order of the Indian Empire (CIE).

In 1880 Arbuthnot returned to England, his term on the Executive Council having come to an end.

The property, owned to 1879 by Edmund Arbuthnot, then came to him through a family connection, on the death in 1889 of William Chatteris of Sandleford Priory, whose first wife Anne was Arbuthnot's sister.

[3] Arbuthnot contributed to the Dictionary of National Biography from its inception in 1885.
