William Hemphill Jones (October 26, 1811 – April 30, 1880) was an American politician in Delaware.
He studied law in Philadelphia with Joseph R. Ingersoll, and when admitted to the bar returned to Wilmington.
Soon after, on his removal to the city of Washington, he was appointed to a position in the Treasury Department, and in December, 1858, was made Chief Clerk in the office of the First Comptroller, and during his long service in that position was repeatedly entrusted with trusts of the highest responsibility, which he executed with fidelity and success.
At the opening of the 45th Congress, in December, 1877, he was made Secretary of the Committee of Ways and Means of the House of Representatives.
