The 1966 United States Senate election in Arkansas took place on November 8, 1966. Incumbent U.S. Senator John L. McClellan was re-elected to a fifth term in office.

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.
