The following outline is provided as an overview of and topical guide to criminal law, a body of law that relates to crime. It proscribes conduct perceived as threatening, harmful, or otherwise endangering to the property, health, safety, and moral welfare of people inclusive of one's self. Most criminal law is established by statute, which is to say that the laws are enacted by a legislature. Criminal law includes the punishment and rehabilitation of people who violate such laws. Criminal law varies according to jurisdiction, and differs from civil law, where emphasis is more on dispute resolution and victim compensation, rather than on punishment or rehabilitation.

Types of criminal law

• Retribution - Criminals ought to suffer in some way. This is the most widely seen goal. Criminals have taken improper advantage, or inflicted unfair detriment, upon others and consequently, the criminal law will put criminals at some unpleasant disadvantage to "balance the scales." People submit to the law to receive the right not to be murdered and if people contravene these laws, they surrender the rights granted to them by the law. Thus, one who murders may be murdered himself. A related theory includes the idea of "righting the balance."
• Deterrence - Individual deterrence is aimed toward the specific offender. The aim is to impose a sufficient penalty to discourage the offender from criminal behavior. General deterrence aims at society at large. By imposing a penalty on those who commit offenses, other individuals are discouraged from committing those offenses.
• Incapacitation - Designed simply to keep criminals away from society so that the public is protected from their misconduct. This is often achieved through prison sentences today. The death penalty or banishment have served the same purpose.
• Rehabilitation - Aims at transforming an offender into a valuable member of society. Its primary goal is to prevent further offense by convincing the offender that their conduct was wrong.
• Restitution - This is a victim-oriented theory of punishment. The goal is to repair, through state authority, any hurt inflicted on the victim by the offender. For example, one who embezzles will be required to repay the amount improperly acquired. Restitution is commonly combined with other main goals of criminal justice and is closely related to concepts in the civil law.
