William Blathwayt (1649 – 21 April 1717) was an English civil servant and colonial administrator who played a central role in the development of the British Empire’s trade and military administration during the late 17th and early 18th centuries. He served as Secretary at War (1689 – 1700) and as a leading member of the Board of Trade and Plantations, where he oversaw the collection of detailed information on the American and Caribbean colonies and helped shape early imperial policy.

Career
Secretary at War (1689–1700)
- Appointed shortly after the Glorious Revolution, Blathwayt became responsible for the administration of the English army’s finances, provisioning, and correspondence.

Board of Trade and Plantations (1693–1709)
- Joined the newly formed Board of Trade, an advisory body to the Crown on colonial and commercial matters.
- Served as the Board’s principal clerk and later as its senior commissioner, supervising the gathering of statistical and economic data from the American, Caribbean, and West‑African colonies.
- Authored the Survey of the British Plantations (published 1700), a comprehensive reference that detailed the geography, resources, governance, and trade of the colonies. This work informed subsequent legislation, including the 1707 Plantation Act.

- Died on 21 April 1717 at his residence, Dyrham Park. He was buried in the parish church of St James, Dyrham.
Legacy
