The 1956 United States Senate special election in Colorado took place on November 6, 1956. Incumbent Republican Senator Eugene Millikin declined to seek re-election to a third term and a competitive election ensued. Former Congressman John A. Carroll, in his third consecutive bid for the Senate, narrowly defeated former U.S. Secretary of Agriculture Charles F. Brannan in the Democratic primary and advanced to the general election, where he faced Governor Dan Thornton, the Republican nominee. Despite Democratic presidential nominee Adlai Stevenson's poor performance in Colorado, state-level Democrats fared much better. Carroll ended up narrowly defeating Thornton, winning his only term in the U.S. Senate.
