Aboriginal child protection describes services designed specifically for protection of the children of "aboriginal" or indigenous peoples, particularly where these peoples are a minority within a country. They may differ at international, national, legal, cultural, social, professional and program levels from general or mainstream child protection services. Fundamental human rights are a source of many of the differences. Aboriginal child protection may be an integral or a distinct aspect of mainstream services or it may be exercised formally or informally by an aboriginal people itself. There has been controversy about systemic genocide in child protection systems enforced with aboriginal children in post-colonial societies.
