This is a complete list of United States senators during the 98th United States Congress listed by seniority from January 3, 1983, to January 3, 1985.

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 their 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.A Chronological List of United States Senators 1789-Present, via www.Senate.gov1961 U.S Census Report Contains 1960 census results.1971 U.S Census Report Contains 1970 census results.1981 U.S Census Report Contains 1980 census results.
