COATNET (Christian Organisations Against Trafficking NETwork) is an international ecumenical network that unites over 50 organisations, congregations and international networks of Catholic, Orthodox and Protestant identities from around the world with the common aim of combating trafficking in human beings.

The aim of the project is to promote international cooperation for adequate response to trafficking in human beings and optimum transnational assistance to trafficked persons. COATNET provides a platform for communication and exchange of good anti-trafficking practices among its partners, and allows the transfer of information, mutual support, and operational partnership across borders. It supports national initiatives and helps to improve anti-trafficking activities in 30 countries all over the world. Please see "COATNET in the world" for detailed partner information.

As of 1st January 2010 the network operates under the legal authority of Caritas Internationalis, a confederation of 164 Catholic relief, development and social service organisations operating in over 200 countries and territories worldwide. Caritas Ukraine , a member organisation of Caritas Internationalis, is responsible for daily coordination of the project, in close cooperation with the Steering Group of COATNET.
