Senate Seniority List: 111th Congress

Rankings are based on the date the oath of office was taken, except in cases when a Senator resigns after the election and the winner of the election is appointed to fill the remainder of the term. For Senators sworn in on the same date, seniority is determined by prior Senate service, followed by vice presidential, House, Cabinet and gubernatorial service, according to the Senate Rules and Administration Committee. If ties remain, seniority is based first on state population and then alphabetically, if there are two Senators from the same state. The panel provided the ranking information but as a matter of committee policy would not confirm the list.
