The 2018 United States elections will mostly be held on Tuesday, November 6, 2018. These midterm elections will take place in the middle of Republican President Donald Trump's term. All 435 seats in the United States House of Representatives and 34 of the 100 seats in the United States Senate will be contested. 39 state and territorial governorships and numerous other state and local elections will also be contested.

All 33 seats in Senate Class I will be up for election. Additionally, special elections may be held to fill vacancies in the other two Senate Classes.

All 435 voting seats in the United States House of Representatives will be up for election. Additionally, elections will be held to select the Delegate for the District of Columbia as well as the delegates from U.S. territories, with the exception of the Resident Commissioner of Puerto Rico, who serves a four-year term.

The 2018 state elections will impact the redistricting that will follow the 2020 United States Census, as many states task governors and state legislators with drawing new boundaries for state legislative and Congressional districts.

Elections will be held for the governorships of 36 U.S. states and three U.S. territories. Special elections may be held for vacancies in the other states and territories, if required by their state/territorial constitutions.
