Capital punishment in New Hampshire

Capital punishment in the U.S. state of New Hampshire is a legal form of punishment for the crime of capital murder, the only crime for which the death penalty may be imposed in the state. Since 1734, twenty-four people have been executed, with the last execution carried out in 1939. As of 2008, there was one man on "Death Row"; however, there is no execution chamber.

Hanging is the method of execution historically used in the state. Lethal injection is currently the primary legal form of execution, though hanging can be utilized if lethal injection is determined to be "impractical to carry out the punishment of death". Between 1868 and 1939, executions took place at the New Hampshire State Prison for Men in Concord. The long moratorium on executions means that while officially considered a "retentionist" state, only four US states have not performed executions more recently than New Hampshire (Maine, Minnesota, North Dakota, and Wisconsin), and only two countries in the European Union (Sweden and Portugal).
