Mar Emmanuel Nidhiri (1842–1904), also known as Nidhiry Mani Kathanar, was a significant figure in the history of the Syrian Malabar Nasrani church in Kerala. He led the community against the European hegemony over the Saint Thomas Christians and was a popular leader accepted by the factions in the Kerala church. Nidhiri was the second Vicar General of the Syro-Malabar Catholic Church. In 1969, as a tribute to his contribution to Malayalam literature, the Kerala Literary Academy unveiled his portrait in the Academy Hall in Trichur, Kerala.
