List of United States Senators in the 1st Congress by seniority

This is a classification of United States Senators by seniority from March 4, 1789 to March 3, 1791.

The order of service is based on the commencement of the senator's first term, with senators entering service the same day ranked alphabetically. The Senate now assigns an official number to each Senator, which is the second number given in the table.^[1]

During this time, there were no official parties, but senators are labeled as Pro-Administration (P), and Anti-Administration (A).
