Malankara Social Service Society (MSSS) is the development and social work organ of the Catholic Major Archdiocese of Trivandrum. MSSS is registered in 1961, under the Travancore-Cochin Literary Scientific and Charitable Societies Act XII of 1955 of the Indian Union. It is active as an organization promoting socio-economic development of the weaker sections for the past 61 years. MSSS has established the identity among the people, Catholic Church, government institutions and other development agencies as an organization committed to work for the weaker and marginalized. This was possible because of its serving the poor, marginalized and unorganized sections of the people irrespective of their religion, caste, creed or gender. The Project area of MSSS encompasses the entire nation of Indian sub-continent. The United Nations recognized the organization as Special Consultative Status with ECOSOC since 2016 understanding the various development interventions.
