The 1958 United States Senate election in North Dakota took place on November 4, 1958, to elect a member of the United States Senate to represent the State of North Dakota, concurrently with other Class 1 elections to the Senate and various other federal, state, and local elections.
Incumbent Republican Senator William Langer was re-elected to a fourth term, defeating a primary challenge from Lieutenant Governor Francis Clyde Duffy and winning the general election with 57.21% of the vote, defeating Democratic-NPL candidate Raymond G. Vendsel who won 41.49% of the vote.[1] Two independent candidates, Arthur C. Townley and Custer Solem, also ran, had minimal impact on the outcome of the election, winning 1,700 (0.83%) and 973 (0.48%) votes, respectively. Townley was known as the creator of the National Non-Partisan League, and had previously sought North Dakota's other senate seat in 1956. This was the last time North Dakota's class 1 seat was won by a Republican until Kevin Cramer won it in 2018.
