This is a complete list of all people who previously served in the United States Senate. As of September 2024, a total of 2,004 persons have served in the senate (including those currently serving).

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.
