List of United States Senators in the 113th Congress by seniority
For a listing of current Senators, see Seniority in the United States Senate.
This is a classification of United States Senators by seniority from January 3, 2013 to January 3, 2015. It is a historical listing and will contain people who have not served the entire two-year Congress should anyone resign, die, or be expelled.
Order of service is based on the commencement of the senator's first term. Behind this is former service as a senator (only giving the senator seniority within his or her new incoming class), service as Vice President, a House member, a Cabinet secretary, or a governor of a state. The final factor is the population of the senator's state.[1][2][3][4][5]
The 113th Congress was the first Congress since the 103rd Congress (1993-95) without a senator who had served for at least 40 years. The most senior senator, Patrick Leahy, did not reach the 40-year mark until January 3, 2015. From November 7, 1996, when Strom Thurmond reached the 40-year mark during the 104th Congress, until Daniel Inouye died on December 17, 2012, there was always at least one senator who had served for 40 years.

- ↑ John Cornyn's predecessor, Phil Gramm, resigned early so Cornyn could be seated on December 2, 2002, and move into Gramm's office suite 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.
