New Hampshire's 5th State Senate district is one of 24 districts in the New Hampshire Senate. It has been represented by Democrat Suzanne Prentiss since 2020, succeeding fellow Democrat Martha Hennessey.
District 5 covers parts of western Grafton, Merrimack, and Sullivan Counties, including the towns of Canaan, Cornish, Dorchester, Enfield, Grantham, Groton, Hanover, Lebanon, Lyme, New London, Orford, Plainfield, Plymouth, Springfield, and Wentworth.
The district is located entirely within New Hampshire's 2nd congressional district. It borders the state of Vermont.
These results happened prior to 2012 redistricting, and thus occurred under different district lines.
