Jamalpur-3 is a constituency represented in the Jatiya Sangsad (National Parliament) of Bangladesh since 1991 by Mirza Azam of the Awami League.
The constituency encompasses Madarganj and Melandaha upazilas.
The constituency was created in 1978 from the Mymensingh-13 constituency when the former Mymensingh District was split into two districts: Jamalpur and Mymensingh.
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 expanded the boundaries of the constituency. Previously it had excluded two union parishads of Melandaha Upazila: Mahmudpur and Shaympur.
Mirza Azam was re-elected unopposed in the 2014 general election after opposition parties withdrew their candidacies in a boycott of the election.
