Mennonite Christian Service Fellowship of India is an inter-Mennonite agency that networks nine Mennonite-related denominations in India to each other.

MCSFI is an inter-Mennonite organization formed in 1963 to encourage informal fellowship between the several conference groups established by western missions in India. Since then, the fellowship has grown to include indigenous churches, and even one conference outside of India (Nepal). MCSFI organizes regular gatherings of pastors, women and youth, and runs social service and disaster relief projects both within the regions of the divers member bodies, and in unreached areas of India.
