List of United States senators in the 118th Congress

For a full description of seniority, an explanation of its rules, and the current list, see Seniority in the United States Senate.

This is a complete list of United States senators during the 118th United States Congress listed by seniority, from January 3, 2023, to January 3, 2025. 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]}

In this Congress, the most junior senior senator is Jon Ossoff, and Maria Cantwell is the most senior junior senator.
