William Henry Sneed (August 27, 1812 – September 18, 1869) was an American attorney and politician, active initially in Murfreesboro, Tennessee, and later in Knoxville, Tennessee, during the mid-19th century.
He was a member of the United States House of Representatives for Tennessee's 2nd congressional district during the Thirty-fourth Congress (1855–1857).
In the months leading up to the Civil War, he became a leader of Knoxville's secessionist movement.
Along with his successful career as an attorney, Sneed was involved in a number of business ventures, most notably the Lamar House Hotel, which he purchased in 1856.
