The 64th 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 March 4, 1915, to March 4, 1917, during the third and fourth years of Woodrow Wilson's presidency. The apportionment of seats in the House of Representatives was based on the 1910 United States census.

The Democrats maintained a majority in both chambers (albeit reduced in the House), and along with president Wilson also maintained an overall federal government trifecta.

Prior to the 64th Congress, per Article 1, Section 3, Clause 1 of the Constitution, all senators had been "chosen by the [State] Legislature thereof." (As a practical matter many senators had been "elected" however technically those elections were subject to affirmation by the State Legislatures.)[1]

However, 32 senators of the 64th Congress - those of Senate Class 3 - were directly elected by popular vote in the 1914 United States Senate Elections as directed by the 17th Amendment. The 17th stipulated that it "...shall not be so construed as to affect the election or term of any senator chosen before it becomes valid as part of the Constitution." Thus Class 1 and 2 senators were not subject to election until 1916 and 1918 respectively. (Note however that should a senator have perished prior to the end of his term then their replacement would have been subject to direct election as they would not have been "chosen before" ratification. This is why Augustus Bacon was the first senator constitutionally elected on July 15, 1913.)[1]
