# List of United States senators in the 119th Congress

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.
In this Congress, Maria Cantwell is the most senior junior senator. JD Vance was the most 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 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.
