Bầu cử Thượng viện Hoa Kỳ tại Alaska năm 1974

The 1974 United States Senate election in Alaska took place on November 5, 1974. Incumbent Democratic U.S. Senator Mike Gravel was re-elected to a second term in office, defeating Republican State Senator Clyde "C.R." Lewis. This is the last time that a member of the Democratic Party has won the Class 3 Senate seat in Alaska. It is also the last time a person not named Murkowski has won this seat. Since this election, Democrats have only won a single subsequent Alaska U.S. Senate race (in 2008).
