William Huston Natcher (September 11, 1909 – March 29, 1994) was a Democratic congressman, serving in the United States House of Representatives from 1953 until his death from heart failure in Bethesda, Maryland in 1994.

On the day of his last vote, he arrived at the Capitol from Bethesda Naval Hospital by ambulance and was wheeled onto the House floor on a gurney.

On March 4, 1994, Natcher was presented with the Presidential Citizens Medal by President of the United States Bill Clinton.

Natcher helped get the majority of federal funding for the new bridge, which now carries U.S. Highway 231 across the Ohio River between Maceo, Kentucky and Rockport, Indiana.

Building 45 of the National Institutes of Health (NIH) in Bethesda, Maryland, is named in his honor.

Natcher was a pro-highway Congressman, encouraging road projects, including in the District of Columbia.

Eventually, a coalition of Congressmen led by Robert Giaimo[15] circumvented Natcher, preventing construction of the Bridge.
