List of former members of the U.S. Senate

This is a complete list of all people who previously served in the United States Senate.

In the party affiliation column, if a Senator switched parties and served non-consecutive terms, their affiliation for each term is listed on the corresponding line. If one of these Senators also served multiple non-consecutive terms with the same party, a quotation mark indicates that their affiliation did not change between that term and their preceding term.
