A corrections officer, correctional officer, detention officer, prison warder, or a prison officer is a person charged with the responsibility of the supervision, safety and security of prisoners in a prison, jail, or similar form of secure custody. Historically, terms such as jailer (also spelled jailor or gaoler), jail guard, prison guard, and turnkey have also been used.

These officers are responsible for the care, custody, and control of individuals who have been arrested and are awaiting trial while on remand or who have been convicted of a crime and sentenced to serve time in a prison or jail. They are also responsible for the safety and security of the facility itself. Most prison officers are employed by the government of the country in which they operate, though some are employed by private companies.
