The suburbs of Johannesburg are officially demarcated areas within the city of Johannesburg, South Africa. As in other Commonwealth countries, the term suburb refers to a "neighbourhood", although the term has a somewhat stronger meaning in South Africa as most (but not all) "suburbs" have legally recognised borders (see legal definition of township) and often (but not always) separate postal codes. The municipal functions for the area, such as municipal policing and social services, are still managed by either the local region or the city government.
