General elections are often the focal point of election-year media coverage as they determine control of elected offices up and down the ballot. Primary elections, however, can provide insight on future elections as they help dictate the direction each party takes.
Although many of the most competitive primaries take place for open seats or offices that are held by a different party, even high-ranking federal officeholders can lose renomination to primary challengers. In the 2014 primary for Virginia's 7th Congressional District, House Majority Leader Eric Cantor (R), ranked behind only then-Speaker John Boehner (R) in Republican House leadership, was defeated by economics professor Dave Brat (R).
On this page, you will find information on noteworthy and notable Republican and Democratic primaries that took place for the U.S. House in 2026. The page also includes information about notable top-two primaries for Republican and Democratic seats.

So far, Ballotpedia has not identified any top-two battleground primaries for Democratic-held seats in 2026.
California uses a top-two primary system, in which all candidates appear on the same ballot. The top two vote-getters, regardless of party affiliation, move on to the general election. In states that do not use a top-two system, all parties are usually able to put forward a candidate for the general election if they choose to.[1][2]
Unlike the top-two format used in some states (Louisiana and Georgia special elections for example), a general election between the top-two candidates in California occurs regardless of whether the top candidate received 50% of the vote in the first round of elections.
As of October 2025, California was one of five states to use a top-two primary system, or a variation of the top-two system for some or all statewide primaries. See here for more information.
