Nongpok Ningthou, also known as the Sovereign of the East or King of the East, is a deity in Sanamahism, the indigenous religion of Manipur. He is the ruling guardian deity of the eastern direction. Legend says Nongpok Ningthou and his consort Panthoibi were united in the Nongmaiching Ching mountains. Later, they were worshipped as the civilization giving deities in Meitei religion.
The five deities venerated in the five divisions of the Selloi Langmai hills gradually merged into one God with the name "Langmai Ningthou" (lit. King of the Langmais).
