The 115th United States Congress was a meeting of the legislative branch of the United States of America federal government, composed of the Senate and the House of Representatives. It met in Washington, D.C., from January 3, 2017, to January 3, 2019, during the final weeks of Barack Obama's presidency and the first two years of Donald Trump's first presidency. The seats in the House were apportioned based on the 2010 United States census.

The Republican Party retained their majority in both the House and the Senate, and, with the inauguration of Donald Trump on January 20, 2017, attained an overall federal government trifecta, a position they had last attained in 2005 with the 109th Congress.

Several political scientists described the legislative accomplishments of this Congress as modest, considering that both Congress and the presidency were under unified Republican Party control.
