Walter Leake (May 25, 1762 – November 17, 1825) served as a United States Senator from Mississippi (1817–1820) and as third Governor of Mississippi (1822–1825).

He was the first Governor of Mississippi to die in office. Leake County, Mississippi, as well as Leakesville, Mississippi are named for him.

A native Virginian, he was born in 1762 in Albemarle County, Virginia, the son of Captain Mask Leake and nephew of Rev. Samuel Leake (Princeton University graduate and a member of the first Board of Trustees of Hampden-Sydney College), an ancestor of Senator John McCain of Arizona. Walter Leake's daughter, Susan Wingfield Leake, married 1807 Henry Goodloe Johnston of Spotsylvania Co., VA and was an ancestor of Haley Reeves Barbour, the current Governor of Mississippi.
