Pentecostal Saint Thomas Christians, also called Pentecostal Syrian Christians, are the ethnic Saint Thomas Christians (Nasranis) affiliated to various Pentecostal and independent Neo-Charismatic churches. Sometimes, the Kerala Brethren are also erroneously lumped together with Pentecostals. The community is native to the Indian state of Kerala, and shares in the legacy of early Christianity in the region, traditionally traced to the missionary activities of Saint Thomas the Apostle in the first century (AD 52–72). Prior to their conversion to Pentecostalism, they belonged to traditional Saint Thomas Christian denominations.
