The 1930 United States Senate special election in Tennessee took place on November 4, 1930, concurrently with other elections to the United States Senate as well as elections to the United States House of Representatives and various state and local elections. The special election came upon the death of incumbent Democratic Senator Lawrence D. Tyson.East Tennessee Historical Society, Mary Rothrock (ed.), The French Broad-Holston Country: A History of Knox County, Tennessee (Knoxville, Tenn.: East Tennessee Historical Society, 1972), pp. 498–499. Democratic Governor Henry Hollis Horton appointed William E. Brock.

In the special election, Brock was elected to fulfill the balance of Tyson's term, but he did not run for the full six-year term that was on the ballot at the same time, and his service as a U.S. senator ended on March 3, 1931. He was succeeded by Cordell Hull who won the succeeding term ballot.
