Capital punishment in the United Kingdom predates the formation of the UK, having been used within the British Isles from ancient times until the second half of the 20th century. The last executions in the United Kingdom were by hanging, and took place in 1964; capital punishment for murder was suspended in 1965 and finally abolished in 1969. Although unused, the death penalty remained a legally defined punishment for certain offences such as treason until it was completely abolished in 1998; the last execution for treason took place in 1946. In 2004, Protocol No. 13 to the European Convention on Human Rights became binding on the United Kingdom; it prohibits the restoration of the death penalty as long as the UK is a party to the convention.

As of 2023, only New Hampshire has a law specifying hanging as an available secondary method of execution, and even then only for the one remaining capital punishment sentence in the state.
