The Ibanag language (also Ybanag or Ibanak) is spoken by up to 500,000 speakers, most particularly by the Ibanag people, in the Philippines, in the northeastern provinces of Isabela and Cagayan, especially in Tuguegarao City, Solana, Abulug, Cabagan, and Ilagan City and with overseas immigrants in countries located in the Middle East, United Kingdom and the United States. Most of the speakers can also speak Ilocano, the lingua franca of northern Luzon island. The name Ibanag comes from the prefix "I" which means "people of", and "bannag", meaning river. It is closely related to Gaddang, Itawis, Agta, Atta, Yogad, Isneg, and Malaweg.
