Brahmanbaria-4 is a constituency represented in the Jatiya Sangsad (National Parliament) of Bangladesh. Since 6 August 2024, the constituency remains vacant.
The constituency encompasses Akhaura and Kasba upazilas.
The constituency was created in 1984 from the Comilla-4 constituency when the former Comilla District was split into three districts: Brahmanbaria, Comilla, and Chandpur.
Anisul Huq was elected unopposed in the 2014 general election after opposition parties withdrew their candidacies in a boycott of the election.
