The 90th 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, 1967, to January 3, 1969, during the last two years of President Lyndon B. Johnson's second term in office.

The apportionment of seats in this House of Representatives was based on the 1960 United States census.

Both chambers had a Democratic majority; however, the Democrats lost seats in both the Senate and the House, which cost them both their 2/3rds supermajority in the Senate and their supermajority status in the House. Along with President Johnson, the Democrats maintained an overall federal government trifecta.
