The constituency encompasses the entirety of Ramganj Upazila, integrating the area under a single administrative and electoral boundary.
The constituency was created in 1984 from a Noakhali constituency when the former Noakhali District was split into three districts: Feni, Noakhali, and Lakshmipur.
