The U.S. Senate election, 1966 was an election on November 8, 1966 for the United States Senate which occurred midway through the term of President Lyndon Baines Johnson. As in many midterm elections, and with divisions over Vietnam in the Democratic base, the Republican opposition took three Democratic seats, but the balance remained overwhelmingly in favor of the Democrats, who retained a 64-36 majority.
Republicans won two open seats in Oregon and Tennessee and defeated incumbent Paul Douglas (D-IL).
In 1968, Republican Charles E. Goodell was appointed to the seat of assassinated presidential candidate Robert F. Kennedy (D-NY). This is not included in the party balances.
