The 2026 U.S. House elections in New Hampshire will be held on November 3, 2026, with primaries on September 8, 2026, to elect the state's two representatives. In the 1st District, incumbent Democrat Chris Pappas is retiring to run for the U.S. Senate, leaving an open seat; the Democratic primary was won by Stefany Shaheen, daughter of Senator Jeanne Shaheen, while the Republican primary went to auto dealer Anthony DiLorenzo. In the 2nd District, incumbent Democrat Maggie Goodlander is seeking re-election and won her primary, while the Republican primary was won by Lily Tang Williams, a former chair of the Colorado Libertarian Party who previously ran for the seat. The 2nd District also features an independent candidate, Robbie Mahrou, in the general election. These elections coincide with other federal and state races, making the 1st District a key battleground due to Pappas's departure.
