How many U.S. Senators are there?

The number of U.S. Senators is one hundred. This is established by the Constitution, specifically Article I, which states that the United States Senate shall be composed of two Senators from each state, regardless of the state’s population. Since there are fifty states in the country, this results in a total of one hundred Senators. Each Senator serves a six-year term, and Senate elections are staggered so that approximately one-third of the Senate is up for election every two years. This structure ensures that there is continuity in the legislative process while allowing for periodic electoral accountability.
