There are 100 senators in the United States Senate.

Basic breakdown

  • The U.S. has 50 states, and each state is represented by 2 senators.
  • 50 states × 2 senators per state = 100 senators in total.

Extra context

  • This number has been fixed at 100 since Hawaii became the 50th state in 1959.
  • Senators serve staggered six-year terms, so roughly one-third of the 100 seats are up for election every two years.
