A probation or parole officer is an official appointed or sworn to investigate, report on, and supervise the conduct of convicted offenders on probation or those released from incarceration to community supervision such as parole. Most probation and parole officers are employed by the government of the jurisdiction in which they operate, although some are employed by private companies that provide contracted services to the government.

Probation in criminal law is a period of supervision over an offender, ordered by the court often in lieu of incarceration.
