This is a complete list of all people who previously served in the United States Senate. As of October 2023^[update], a total of 2,003 persons have served in the senate (including those currently serving).^[1]

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.
