Henry Toole Clark (February 7, 1808 – April 14, 1874) was the 36th Governor of the U.S. state of North Carolina from 1861 to 1862 during the American Civil War.

The Clarks were members of that elite planter class that dominated social and political thought in eastern North Carolina.

He spent most of his time managing the family's extensive land and slave holdings in North Carolina, Alabama, and Tennessee.

As the leader of the state in that formative period, he mobilized thousands of soldiers for the Southern cause, established the only Confederate prison in North Carolina, arranged the production of salt for the war effort, created European purchasing connections, and built a successful and important gunpowder mill.

As governor, he was unable to maneuver in the new political world ushered in by the Civil War, and he retired abruptly from public service at the end of his term in September 1862.
