With contemporary issues Zambia faces, ranging from Economic, political, healthy related or environmental, the government has a tough mandate to provide social services to every citizen in the country. To help with this problem, an aggregate of organizations called Civil Society Organizations (CSOs) like Faith Based Organizations (FBOs), Non-governmental Organizations (NGOs) and Community Based Organizations (CBOs), collectively known as the Civil Society come in to complement in the provision of these social services using local and international Civil Society Organizations (CSOs). The civil society is a complementary player to the government (Public Sector) and the Private Sector filling in the gaps where both the private and public sectors have not managed to adequately provide the social services, which creates communities to be isolated, marginalized and even become poor.
This paper will analyze the Civil society in Zambia with emphasis on the international Civil society organizations (CSOs). Example of notable international CSOs in Zambia are, the International Community of the Red Cross (ICRC), World Vision, United States Agency for International Development (USAID), World Renew, Catholic Medical Mission Board (CMMB), UN-Habitat, United Nations International Children’s Emergency Fund (UNICEF), WaterAid, Care International, just to mention a few. 
This research will outline the contribution made by the international CSOs in Zambia towards the wellbeing of the poor and marginalized members of the society and the challenges they face as they care out these humanitarian aid.
