The Eighty-ninth United States Congress was a meeting of the legislative branch of the United States federal government, composed of the United States Senate and the United States House of Representatives. It met in Washington, DC from January 3, 1965 to January 3, 1967, during the third and fourth years of Lyndon Johnson's presidency. The apportionment of seats in the House of Representatives was based on the Eighteenth Census of the United States in 1960. Both chambers had a Democratic supermajority. It is regarded as "arguably the most productive in American history". Some of its landmark legislation includes Social Security Amendments of 1965 (the creation of Medicare and Medicaid), the Voting Rights Act, Higher Education Act, and Freedom of Information Act.
The count below identifies party affiliations at the beginning of the first session of this Congress, and includes members from vacancies and newly admitted states, when they were first seated. Changes resulting from subsequent replacements are shown below in the "Changes in membership" section.
This list is arranged by chamber, then by state. Senators are listed in order of seniority, and Representatives are listed by district.
Senators are popularly elected statewide every two years, with one-third beginning new six-year terms with each Congress. Preceding the names in the list below are Senate class numbers, which indicate the cycle of their election. In this Congress, Class 1 meant their term began in this Congress, requiring reelection in 1970; Class 2 meant their term ended with this Congress, requiring reelection in 1966; and Class 3 meant their term began in the last Congress, requiring reelection in 1968.
