Prison visitor

A prison visitor is a person who visits prisons to befriend and monitor the welfare of prisoners in general, as distinct from a person who visits a specific prisoner to whom they have a prior connection. Prisons may also have a visiting committee.

Organizations
There are voluntary organisations of prison visitors in many jurisdictions, some of which have official recognition. Examples include:
 * National Association of Official Prison Visitors in the United Kingdom
 * Prisoners' Friends' Association in Hong Kong
 * Prisoner Visitation and Support in the United States
 * Norwegian Red Cross in Norway
