Before 1984, it was a mahakuma of Noakhali district. In 1872–74, Amirgaon thana which was established by the Mughals was facing river erosion. Then it was moved to Khaiarat which was situated by the river Feni. Then this area was known as Feni because of the river. In 1976, a new mahakuma was established and the Khaiarat thana was moved to this new mahakuma and the mahakuma was named Feni. The first headquarter of the mahakuma was in Amirgaon thana. It was moved to Feni in 1881. During the administrative reconstruction in 1984, all the  were upgraded to districts and Feni became one of them. Etymology
