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 first presidency. Senators elected to regular terms in 2014 finished their terms in this Congress, and House seats were apportioned based on the 2010 census. In the November 2018 midterm elections, the Democratic Party won a new majority in the House, while the Republican Party increased its majority in the Senate. Consequently, this was the first split Congress since the 113th Congress of 2013–2015, and the first Republican Senate–Democratic House split since the 99th Congress of 1985–1987. This Congress was the youngest incoming class by mean age, compared to the previous three the incoming class of freshman representatives, and the most demographically diverse in history. Upon joining the Libertarian Party on May 1, 2020, Justin Amash became the first member of Congress to represent a political party other than the Democrats or the Republicans since Rep. William Carney, who served as a Conservative before switching to the Republican Party in 1985. Before joining the Libertarian Party, Amash had been serving as an independent since his departure from the Republican Party on July 4, 2019. Paul Mitchell also left the Republicans in December 2020, becoming an independent. Neither incumbent ran for re-election.

The Senate included 74 men and 26 women, the most women to date. In 6 states, both senators were women; 14 states were represented by 1 man and 1 woman; and 30 states were represented by 2 men. During this Congress, Johnny Isakson retired for health reasons and Kelly Loeffler was appointed, which increased the number of women from 25 after the 2018 elections to 26. There were 91 non-Hispanic white, 4 Hispanic, 2 Black, 2 Asian, and 1 multiracial (Black/Asian) senators. Additionally, 2 senators were LGBTQ+.

House of Representatives

There were 101 women in the House, the largest number in history. There were 313 non-Hispanic white, 56 Black, 44 Hispanic, 15 Asian, and 4 Native American congress members. Eight were LGBTQ+. Two Democrats — Alexandria Ocasio-Cortez and Donna Shalala — were the youngest (30) and oldest (78) freshmen women in history. Freshmen Rashida Tlaib (D-MI) and Ilhan Omar (DFL-MN) were the first two Muslim women and freshmen Sharice Davids (D-KS) and Deb Haaland (D-NM) were the first two Native American women elected as well. The average age of Members of the House at the beginning of the 116th Congress was 57.6 years. With the election of Carolyn Maloney as the first woman to chair the House Oversight Committee, women chaired a record six House committees in a single Congress (out of 26 women to ever chair House committees in the history of Congress), including House members Maxine Waters (Financial Services), Nita Lowey (Appropriations), Zoe Lofgren (Administration), Eddie Bernice Johnson (Science, Space and Technology) and Nydia Velázquez (Small Business), as well as Kathy Castor, who chaired the Select Committee on the Climate Crisis. In addition, women chaired a record 39 House subcommittees. Lowey and Kay Granger were also the first women to serve as chair and ranking member of the same committee in the same Congress since the since-defunct Select Committee on the House Beauty Shop, which was chaired and populated entirely by congresswomen during its existence from 1967 to 1977.

Diversity of the freshman class

The demographics of the 116th U.S. Congress freshmen were more diverse than any previous incoming class. At least 25 new congressional representatives were Hispanic, Native American, or people of color, and the incoming class included the first Native American women, the first Muslim women, and the two youngest women ever elected. The 116th Congress included more women elected to the House than any previous Congress.
