Life imprisonment is a legal penalty in Singapore. This sentence is applicable for more than forty offences under Singapore law, such as culpable homicide not amounting to murder, attempted murder, kidnapping by ransom, criminal breach of trust by a public servant, voluntarily causing grievous hurt with dangerous weapons, and trafficking of firearms, in addition to caning or a fine for certain offences that warrant life imprisonment.

The Penal Code 1871 sets out general principles of the criminal law of Singapore, as well as the elements and penalties of general criminal offences such as assault, criminal intimidation, mischief, grievous hurt, theft, extortion, sex crimes and cheating. The Penal Code does not define and list exhaustively all the criminal offences applicable in Singapore – a large number of these are created by other statutes such as the Arms Offences Act, Kidnapping Act, Misuse of Drugs Act and Vandalism Act.
