The 116th United States Congress was a meeting of the legislative branch of the United States federal government, composed of the Senate and the House of Representatives. It convened in Washington, D.C., on January 3, 2019, and ended on January 3, 2021, during the final two years of Donald Trump's presidency. Senators elected to regular terms in 2014 finished their terms in this Congress, and House seats were apportioned based on the 2010 census.

The 2018 United States House of Representatives elections were held on November 6, 2018, as part of the 2018 midterm elections during President Donald Trump's term, with early voting taking place in some states in the weeks preceding that date. Voters chose representatives from all 435 congressional districts across each of the 50 U.S. states to serve in the 116th United States Congress. Non-voting delegates from the District of Columbia and four of the five inhabited U.S. territories were also elected. On Election Day, Republicans had held a House majority since January 2011.
