Henry Whitely was a businessman, railroad executive, and Federalist politician from the U.S. state of Delaware. In 1816, Whitely, along with James Price and eight others, were appointed commissioners of the planned Wilmington and Christiana Turnpike. In 1818, he bought a stone house and 100 acres of land in Newark, Delaware. (The house still stands today; in 1983, it was added to the National Register of Historic Places.) From October 1817 through September 1821, Whitely served in the Delaware House of Representatives. In 1833, he became a director of the Farmers' Bank of Delaware.
