Brahmanbaria-1 is a constituency represented in the Jatiya Sangsad (National Parliament) of Bangladesh since January 2024 by Syed A.K. Ekramuzzaman of the independent politician .
The constituency encompasses Nasirnagar Upazila.
The constituency was created in 1984 from the Comilla-6 constituency when the former Comilla District was split into three districts: Brahmanbaria, Comilla, and Chandpur.
Ahead of the 2008 general election, the Election Commission redrew constituency boundaries to reflect population changes revealed by the 2001 Bangladesh census. The 2008 redistricting altered the boundaries of the constituency.
Ahead of the 2014 general election, the Election Commission reduced the boundaries of the constituency. Previously the constituency had included three union parishads of Brahmanbaria Sadar Upazila (after 2010, the new Bijoynagar Upazila): Budhanti, Chandura, and Harashpur.
Mohammad Sayedul Haque died in December 2017. Bodruddoza Md. Farhad Hossain of the Awami League was elected in a March 2018 by-election.
