A gibbet /ˈdʒɪbɪt/ is any instrument of public execution (including guillotine, executioner's block, impalement stake, hanging gallows, or related scaffold), but gibbeting refers to the use of a gallows-type structure from which the dead or dying bodies of executed criminals were hanged on public display to deter other existing or potential criminals. In earlier times up to the late 18th century, live gibbeting also took place in which the condemned was placed alive in a metal cage and left to die of thirst. The term gibbet may also be used to refer to the practice of placing a criminal on display within a gibbet. This practice is also called "hanging in chains".

Gibbeting was a common law punishment, which a judge could impose in addition to execution. This practice was regularised in England by the Murder Act 1751, which empowered judges to impose this for murder. It was most often used for traitors, murderers, highwaymen, pirates, and sheep stealers and was intended to discourage others from committing similar offences. The structures were therefore often placed next to public highways (frequently at crossroads) and waterways.

Exhibiting a body could backfire against a monarch, especially if the monarch was unpopular. The rebels Henry of Montfort and Henry of Wylynton, enemies of Edward II, were drawn and hanged before being exhibited on a gibbet near Bristol. However, the people made relics of these bloody and mutilated remains out of respect and later used the relics in violent protest. Miracles were even reported at the spot where the bodies were hanging.
