The 1930 United States Senate election in Kentucky took place on November 4, 1930, alongside a special election to the same seat.
Incumbent Senator Frederic M. Sackett resigned on January 9, 1930, to become Ambassador to Germany. Governor Flem D. Sampson appointed U.S. Representative John M. Robsion to fill Sackett's seat until a successor could be duly elected. Robsion lost both the special election to complete the term and the regularly scheduled 1930 election, both held on November 4.
