Barguna-1 is a constituency represented in the Jatiya Sangsad (National Parliament) of Bangladesh.
The constituency encompasses Amtali, Barguna Sadar, and Taltali upazilas.
The constituency was created in 1984 from a Patuakhali constituency when the former Patuakhali District was split into two districts: Barguna and Patuakhali.
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.
