The 1922 United States Senate election in North Dakota took place on November 7, 1922. Incumbent Republican Senator Porter J. McCumber sought re-election, but was defeated in the Republican primary by Lynn Frazier, the former Governor of North Dakota, who had been recalled in 1921. In the general election, Frazier faced former State Representative James Francis Thaddeus O'Connor, the Democratic nominee. Even as Republicans did poorly nationwide, Frazier narrowly defeated O'Connor to hold the seat.
