The 1966 United States Senate election in Georgia was held on November 8, 1966. Incumbent Democratic Senator Richard Russell Jr. was elected to a seventh term in office.
On September 14, Russell won the Democratic primary with 90.59% of the vote against only nominal opposition from fellow Democrat Harry Hyde. At this time, Georgia was a one-party state and the Democratic nomination was tantamount to victory. No Republican had run for Senate in Georgia since 1932.[1] Russell won the November general election without an opponent.
Russell did not complete his term; he died in January 1971.
