The MCC Alumni Association, known as “Christian College Day Association” was formed in 1891 and is the oldest of its kind in India. In December 1963, the Association implemented a new constitution and changed its name to “Alumni Association” with the stated objectives of the development of the College and fostering of cultural and social interests of the alumni through meetings and publications. The Alumni and Public Relations Office was set up in 1962 and it looks after the activities of the Association.
Over the years, the Association has supported many noble causes in the College including the 83 construction of the Devanesen Memorial theatre, the Miller Memorial Library, the International Guest House, the C. A. Abraham Pavilion and the compound wall. Today, the association has 22 chapters in India and 11 chapters in other parts of the world. When a student leaves the College at the end of the course, he/she automatically becomes an annual member of the Association. One can then choose to become a permanent member, along with a long list of outstanding alumni, such as Dr S. Radhakrishnan, Dr A.L. Mudaliar, Dr Raja Ramanna, Mr T.T. Krishamachari, Mr Eric Prabhakar, Mr M.M. Rajendran, Mr T.N. Seshan, Mr Mammen Mappillai, Mr Suresh Krishna, Mr C.D. Gopinath, Dr Pratap C. Reddy, Mr K. Vijay Kumar, Mr E.L. Philip, Justice P.D.

Kurien to name a few. Life membership or Donor membership supports several alumni programmes and provides life-time contact with the Alma mater.

Many distinguished alumni from various walks of life enriched this event with their presence.
