The 89th 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, D.C., from January 3, 1965, to January 3, 1967, during the second and third years of Lyndon B. Johnson's presidency. The apportionment of seats in the House of Representatives was based on the 1960 United States census.

Both chambers had a Democratic supermajority, and with the election of President Lyndon B. Johnson to his own term in office, maintaining an overall federal government trifecta. This is the last time Democrats or any party had a 2/3rd supermajority in the Senate.

Some of its landmark legislation includes Social Security Amendments of 1965 (the creation of Medicare and Medicaid), the Voting Rights Act, the Higher Education Act, the Immigration and Nationality Act of 1965, the Elementary and Secondary Education Act, and the Freedom of Information Act.
