The Diocese of Ilagan (Lat: Dioecesis Ilaganensis) is a Latin Catholic diocese of the Catholic Church in the Philippines. It was erected on 31 January 1970 from territory of the then Roman Catholic Diocese of Tuguegarao and covered the entire civil Province of Isabela. At the time of Ilagan's creation, Tuguegarao was not a Metropolitan diocese and therefore Ilagan fell under the jurisdiction of Archdiocese of Nueva Segovia. It is a suffragan diocese of the Roman Catholic Archdiocese of Tuguegarao since 1974 when Tuguegarao was elevated to an archdiocese.

The diocese has had no jurisdictional changes. The seat of the diocese used to be located in Saint Ferdinand Parish Church in Ilagan City before being transferred to the Gamu Cathedral (Cathedral of Saint Michael the Archangel) in Gamu, Isabela, in 2013.

David William V. Antonio was installed as the fifth Bishop of Ilagan on February 12, 2019.
