New Hampshire's 1st congressional district

New Hampshire's 1st congressional district covers parts of Southern New Hampshire and the eastern portion of the state. The district contains parts of Hillsborough, Rockingham, Merrimack, Grafton, and Belknap counties; and the entirety of Strafford and Carroll counties.

The district contains Manchester, New Hampshire's most populous city, and its immediate suburbs. Most of the district's population resides in Rockingham County, which includes much of the Seacoast Region. The northern part of the district in Belknap, Carroll, and Grafton counties are far more rural.

The district is home to the University of New Hampshire, the state's largest university. Some of the largest employers in the district are Fidelity Investments, J. Jill, Elliot Health System, and The University System of New Hampshire. It is represented in the United States House of Representatives by Democrat Chris Pappas.

The district was identified as a presidential bellwether district by Sabato's Crystal Ball, having voted for the Electoral College winner in the past four presidential elections as of 2020.
