Devasahayam Pillai was an 18th-century Indian civil servant and Catholic martyr from the Travancore kingdom. Born Neelakanta Pillai into a high-caste Hindu family, he served as a court official before converting to Christianity in 1745. This decision led to his removal from government service and subsequent persecution. After facing public humiliation and physical torture, he was exiled to a forested area near Aralvaimozhi, where he died in 1752. He was canonized as a saint by Pope Francis in 2022.
