The New Hampshire at-large congressional district is obsolete, with representation having since been divided into districts.

However, from 1789 to 1847, New Hampshire elected members to the United States House of Representatives at-large:

• From 1789 to 1793, three members represented the state at-large.
• From 1793 to 1803, four members represented the state at-large.
• From 1803 to 1813, five members represented the state at-large.
• From 1813 to 1833, six members represented the state at-large.
• From 1833 to 1843, five members represented the state at-large.
• From 1843 to 1847, four members represented the state at-large.
• In 1847 at-large representation was replaced by four congressional districts.
