Elections for the United States Senate will be held on November 4, 2014, with 33 of the 100 seats in the Senate being contested in regular elections whose winners will serve six-year terms from January 3, 2015, until January 3, 2021. Additionally, special elections may be held to fill vacancies that occur during the 113th United States Congress.

The elections to the House of Representatives, elections for governors in states and territories, and many state and local elections will also be held on this date. The 2014 Senate elections will mark 100 years of direct elections of senators.

After losing ground in the 2012 elections, an internal fight broke out among the Republican leadership in early 2013 over the best strategy and tactics for the 2014 Senate races.^[1]

There are 53 Democratic, 45 Republican and 2 Independent senators. 33 are up for election this year as members of the class 2 Senators, and two are up for special elections (both from class 3). Among the senators up for election in 2014, there are 21 Democrats and 14 Republicans.

There may be some changes if senators die or resign. If senators in other classes die or resign between 2012 and 2014, there may be additional special elections. The dates between which the death or resignation of a senator would lead a special election during this time period vary from state to state.

Shading indicates party with largest share of that line.
