Bầu cử Thượng viện Hoa Kỳ tại Alaska năm 1958

The 1958 United States Senate elections in Alaska were held November 25, 1958. The elections were held in anticipation of Alaska's admission as the forty-ninth state in the union, effective January 3, 1959. The state held two simultaneous elections to determine their first senators.

Both elections were won by the Democratic Party. The new senators, Bob Bartlett and Ernest Gruening, were sworn into office alongside those senators elected in the 1958 United States Senate elections held three weeks earlier.
