The 1948 United States Senate elections were held concurrently with the election of Democratic President Harry S. Truman for a full term. The 32 seats of Class 2 were contested in regular elections, and one special election was held to fill a vacancy. Truman campaigned against an "obstructionist" Congress that had blocked many of his initiatives, and additionally, the U.S. economy recovered from the postwar recession of 1946–1947 by election day. Thus, Truman was rewarded with a Democratic gain of nine seats in the Senate, enough to give them control of the chamber.^[1][2] This was the last time until 2020 that Democrats flipped a chamber of Congress in a presidential election cycle.

There were 2 elections to the same seat, due to the December 15, 1946 death of three-term Democrat Josiah Bailey. Democratic former congressman William B. Umstead was appointed December 18, 1946 to continue Bailey's term, pending a special election.

Umstead supported the conservative Taft–Hartley Act. The Democratic former Governor of North Carolina J. Melville Broughton was seen as a "rather liberal alternative" to Umstead. Broughton beat Umstead in the Democratic primaries and then won the general elections.
