Prohibition of death is a political social phenomenon and taboo in which a law is passed stating that it is illegal to die, usually specifically in a certain political division or in a specific building.

The earliest case of prohibition of death occurred in the 5th century BC, on the Greek island of Delos; dying on Delos was prohibited on religious grounds.

Today, in most cases, the prohibition of death is a satirical response to the government’s failure to approve the expansion of municipal cemeteries. In Spain, one town has prohibited death; in France, there have been several settlements which have had death prohibited; whilst in Biritiba Mirim, in Brazil, an attempt to prohibit death took place in 2005.
There is a falsely rumored prohibition on recording deaths in royal palaces in the United Kingdom, for rather different reasons.
