Feni-3 is a constituency represented in the Jatiya Sangsad (National Parliament) of Bangladesh since 2019 by Masud Uddin Chowdhury of the Jatiya Party (Ershad).
The constituency encompasses Daganbhuiyan and Sonagazi upazilas.
The constituency was created in 1984 from the Noakhali-3 constituency when the former Noakhali District was split into three districts: Feni, Noakhali, and Lakshmipur.
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.
