Every state elects two U.S. Senators to six-year terms, regardless of its population or its number of House districts. This page lists the current U.S. Senators for all 50 states and their party. To find your U.S. House representative instead, enter your address on the home page.
About one third of the Senate is elected every two years, and a state’s two seats sit in different cycles. The last column shows the upcoming election years for each state’s seats among 2026, 2028, and 2030. In 2026, 33 states hold a regular Senate election, plus special elections in Florida and Ohio. For House races, see the 2026 Elections page.

Non-voting delegates
The U.S. House of Representatives also has six non-voting delegates and a resident commissioner who represent the District of Columbia and the U.S. territories: District of Columbia, Puerto Rico, Guam, U.S. Virgin Islands, American Samoa, and Northern Mariana Islands.
Senator names and election years are reviewed against official sources. Seats can change between elections through resignations or appointments. For the official roster, see the U.S. Senate website. To explore the House, use the home page lookup or Browse Districts.
How many senators does each state send to Washington?
Two. Every state elects two U.S. senators regardless of population, which is 100 senators in total. Article I, Section 3 of the Constitution establishes it, and Article V protects it: no state can be deprived of its equal suffrage in the Senate without its consent.
That makes the Senate different from the House, where seats are divided by population. California has 52 House seats and Wyoming has 1, but both have exactly 2 senators.
Six year terms and three classes
Senators serve six year terms. The seats are divided into three classes so that roughly one third of the Senate is up for election every two years, which keeps the chamber continuous rather than replacing it wholesale.
- Class I was last elected in 2024 and is next up in 2030.
- Class II was last elected in 2020 and is on the ballot in November 2026.
- Class III was last elected in 2022 and is next up in 2028.
A state’s two seats sit in different classes, so they are never on the ballot in the same general election. For the seats being decided this year, see the 2026 Senate elections.
When a Senate seat becomes vacant
If a senator dies, resigns or is expelled, the Seventeenth Amendment lets a state legislature allow its governor to appoint a temporary replacement until an election is held. Most states have granted that power, so a vacancy is usually filled by appointment within weeks. A few states require a special election instead. The rules differ state by state, which is why two vacancies in the same month can be handled very differently.
Who your senators represent
Both of your senators represent the entire state, so every voter in the state shares the same two. That differs from the House, where you have exactly one member determined by your address. If you are unsure which House district you live in, use the lookup on the home page.
