The 1932 United States Senate elections in Colorado took place on November 8, 1932. Incumbent Republican Senator Charles W. Waterman announced that he would not seek re-election to a second term. Attorney Karl C. Schuyler won the Republican nomination to succeed Waterman and faced former Senator Alva B. Adams, the Democratic nominee, in the general election. The ensuing elections produced a split result. Schuyler narrowly won the special election over Walker by about 1,000 votes, and ended up serving for several months in the Senate. However, Adams handily defeated Schuyler for the full term.
