Sir Henry Conway Belfield, KCMG, JP (29 November 1855 – 8 January 1923) was an English colonial administrator.
The son of John Belfield, JP, of Primley Hill, South Devon, and of Eliza Conway Bridges, daughter of Captain George Bridges, RN, Belfield was educated at Rugby School in Warwickshire and Oriel College, Oxford.
On the federation of the Malay States in 1896 he became First Commissioner of Lands and Mines, and acted as British Resident of Selangor on several occasions.
Belfield was appointed Governor of the East Africa Protectorate (now Kenya) in 1912, and concurrently High Commissioner of Zanzibar in 1914.
His perceived lack of interest in the East African Campaign led to discontent, and after two unsuccessful attempts he was forced into retirement by the Colonial Office.
