Young persons who, in many states, are treated differently than adult criminals and are tried in special youth courts. In Canada, for example, criminal suspects between 12 and 17 inclusively are processed under the Young Offenders Act, which includes several provisions which reflect the rehabilitative nature of the legislation.

A young offender is a person of either gender who has been convicted or cautioned for a criminal offence. Criminal justice systems often deal with young offenders differently from adult offenders, but different countries apply the term 'young offender' to different age groups depending on the age of criminal responsibility in that country.
