Knute Nelson Republican Magnus Johnson Farmer–Labor The 1923 United States Senate special election in Minnesota took place on July 16, 1923.

The election was held to fill, for the remainder of the unexpired term, the seat in the United States Senate left vacant by Republican U.S.

State Senator Magnus Johnson of the Farmer–Labor Party of Minnesota defeated Governor J.

Johnson's victory marked the first time, since Morton S. Wilkinson took office in 1859, that neither of Minnesota's seats in the United States Senate were held by a Republican.

It also marked the first time, since Wilkinson's assumption of the office, that the person holding Minnesota's Class 2 U.S. Senate seat was not a Republican, and Johnson became just the second non-Republican to ever hold that seat (the first being the Democrat James Shields, whose term of office ended when Wilkinson's began).
