Christianity in Kerala

Christianity is the third-most practised religion in Kerala, accounting for 18% of the population according to the Indian census. Although a minority, the Christian population of Kerala is proportionally much larger than that of India as a whole. A significant portion of the Indian Christian population resides in the state.

The Saint Thomas Christians, also called Syrian Christians or Malankara Nasrani or Nasrani Mappila or Nasrani, are an ethnoreligious community of Malayali Syriac Christians from Kerala, India, who trace their origins to the evangelistic activity of Thomas the Apostle in the 1st century. The term Syrian relates not to their ethnicity but to their historical, religious, and liturgical connection to Syriac Christianity.
