The seniority in the United States Senate is based upon a series of ranked factors; only resorting to the next factor when tied.1
"Senior senator" and "junior senator" are terms commonly used to describe United States senators. Each state sends two senators to serve in the Senate; the longer (continuously) serving of the two is by convention referred to as the senior senator, and the other is referred to as the junior senator. If both are elected at the same time (e.g., one in a regular election and the other simultaneously to fill the seat of a senator who resigned), the one who is sworn in first is senior.
Benefits of seniority
There is no mandated difference in rights or power, although Senate rules give more power to senators with more seniority. Generally, senior senators will have more power, though being a member of the majority party is more advantageous than being senior. In addition, by custom the senior senators from the president's party control federal patronage appointments in their states. Thus being the junior senator is disadvantageous if the senior one is from the same party.
Some of the perquisites of seniority offered by the U.S. Senate:
- Senators are given preferential treatment for committee assignments based on seniority. Although the committee chairmanship is an elected position, it is traditionally given to the most senior senator of the majority party serving on the committee. Ranking member (called vice-chairman in some select committees) of a committee is the most senior member of the minority party thereon.
- Greater seniority enables a senator to choose a desk closer to the front of the Senate Chamber.
- Senators with higher seniority may choose to move into better office space as those offices are vacated.
- Seniority determines the ranking in the United States order of precedence although other factors, such as being a former President or First Lady, can place an individual higher in the order of precedence.
Factors considered
There are 11 factors considered in calculating seniority:
- Amount of consecutive time serving as U.S. senator
- Previous U.S. senator (non-consecutive)
- Length of time serving as a senator in previous non-consecutive terms
- Previous U.S. representative
- Length of time serving as a U.S. representative
- Previous president
- Previous vice president
- Previous cabinet member
- Previous state governor
- Population of state based on the most recent census when the senator took office
- Alphabetical by last name (in the rare instance that two senators came from the same state on the same day and have identical credentials)
Current seniority list
The president pro tempore of the Senate is traditionally the most senior member of the majority party. The current president pro tempore, Robert Byrd, is also the dean of the United States Senate.
Only relevant factors are listed below. For instance, Robert Byrd's time with the House of Representatives no longer has any bearing on his seniority, so it is not listed.
For senators whose seniority is based on their states' respective populations, the state population ranking, as determined by the relevant United States Census2345 is given.

There are two disputed seats: one from Illinois and one from Minnesota |
| 100 |
Disputed seats
Two seats are in dispute.
- Illinois: Illinois Governor Rod Blagojevich appointed Roland Burris to fill the vacancy created by the resignation of Senator (and President-elect) Barack Obama. The Democratic leadership announced it will block Burris from taking the seat due to Blagojevich's alleged previous attempt to sell the seat.16 The Senate's ability to refuse to seat Burris is a matter of debate;17 it is therefore unclear whether or when Burris will take his seat. The seniority rank of whomever takes that seat is unclear at this time.
- Minnesota: Due to a disuputed election between Norm Coleman and Al Franken, neither of them is seated, and eventually one of them will be seated in during the 111th Congress.16 Their seniority will be determined depending on which candidate is seated. Coleman would be expected to retain his seniority, between John Cornyn and Mark Pryor. It is unclear whether Franken's seniority would date back to January 3, 2009, in which case he would rank between Kay Hagan and Jeff Merkley, or the day he is seated, in which case he would rank last.
Upcoming changes expected
At least three changes in membership are expected early in the 111th Congress.
- Colorado: Ken Salazar, if his cabinet appointment is confirmed, will soon be replaced, leading to a vacancy to be filled by appointment, and the other Senator, Mark Udall, would become the Senate's most junior "senior senator". Governor Bill Ritter has announced he will appoint Michael Bennet to Salazar's seat.18
- Delaware: On January 15, 2009, Joe Biden will resign to become Vice President of the United States, and will be replaced by Ted Kaufman.
- New York: Hillary Clinton, if her cabinet appointment is confirmed, will soon resign, leading to a vacancy to be filled by appointment.

Delaware governor Ruth Ann Minner has announced that she will appoint Ted Kaufman as his successor, and Kaufman will be sworn in after all other new Senators have been and thus will be among the last in seniority.

Lautenberg has sought restoration of his seniority based on his prior service, but has not received it. - HillNews.com
- ^ Phil Gramm resigned early, effective November 30, 2002, so that Cornyn could take senate office on December 2, 2002, and move into Gramm's office suite in order to begin organizing his staff. Cornyn did not, however, gain seniority, owing to a 1980 Rules Committee policy that no longer gave seniority to senators who entered Congress early for the purpose of gaining advantageous office space.
- ^ Ken Salazar has been chosen to be Secretary of the Interior and is expected to resign his Senate seat in 2009. (See Upcoming changes expected, above)
- ^ Senator Webb served as Secretary of the Navy; however, that has not been a Cabinet-level position since 1947 and therefore does not affect his Seniority.
