This is a complete list of United States senators during the 119th United States Congress listed by seniority, from January 3, 2025, to January 3, 2027. 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. For senators beginning their terms on the same day, with the same previous service, representing the same state, they are ranked alphabetically by their surname. [1] [2] [3] [4] [5]
In this Congress, Maria Cantwell is the most senior junior senator. JD Vance was the junior senior senator at the start of the Congress until his resignation on January 10, 2025, to become vice president, the distinction is now held by Vance's fellow senate colleague, freshman senator Bernie Moreno.
Alex Padilla is the most junior senator to serve as chair or ranking member of a committee. The most senior senator to not serve as chair or ranking member of a committee is John Cornyn.

The most senior senators by class are Maria Cantwell (D-Washington) from Class 1, Mitch McConnell (R-Kentucky) from Class 2, and Chuck Grassley (R-Iowa) from Class 3. Cantwell is the most senior senator from her class while being the junior senator from her state.
United States senators are conventionally ranked by the length of their tenure in the Senate. The senator in each U.S. state with the longer time in office is known as the senior senator; the other is the junior senator. This convention has no official standing, though seniority confers several benefits, including preference in the choice of committee assignments and physical offices. When senators have been in office for the same length of time, a number of tiebreakers, including previous offices held, are used to determine seniority. By tradition, the longest serving senator of the majority party is named president pro tempore of the Senate, the second-highest office in the Senate and the third in the line of succession to the presidency of the United States.
