Willis Smith (December 19, 1887 – June 26, 1953) was an American attorney and Democratic U.S. senator from the state of North Carolina between 1950 and 1953.

After graduating from Trinity College (now the undergraduate liberal arts college of Duke University) in 1910 and Duke University Law School in 1912, he became a practicing attorney—but interrupted his work to serve in the United States Army during World War I.

Graham had been appointed to fill the vacancy caused by the death of J. Melville Broughton and had served only a little over a year at the time of his defeat.

In a campaign distinguished by race-baiting,[4] Graham, who was well known for his civil rights sympathies, was supported by President Harry Truman and the state's liberal Democratic faction, while Smith was aided by strategist Jesse Helms.

He died due to coronary thrombosis in 1953 in Bethesda, Maryland[5] and was interred at the Historic Oakwood Cemetery in Raleigh, North Carolina.
