1942 United States Senate election in Arkansas

The 1942 United States Senate election in Arkansas took place on November 2, 1942. Incumbent Senator John E. Miller was appointed to a federal judgeship by Franklin Delano Roosevelt, and his appointed replacement Lloyd Spencer rejoined the Navy rather than run for election.

After a highly-competitive four-way primary, U.S. Representative John L. McClellan defeated Arkansas Attorney General Jack Holt in a run-off election.

Because the Republican Party (or any other party) did not field a candidate in the general election, McClellan's primary victory was tantamount to election.

Candidates

 * Clyde T. Ellis, U.S. Representative from Bentonville
 * Jack Holt, Arkansas Attorney General
 * John L. McClellan, U.S. Representative from Camden
 * David D. Terry, U.S. Representative from Little Rock

Results
McClellan was unopposed in the general election.
