Narsingdi-4 is a constituency represented in the Jatiya Sangsad (National Parliament) of Bangladesh. Since 6 August 2024, the constituency remains vacant.
The constituency encompasses Belabo and Manohardi upazilas.
The constituency was created in 1984 from the Dhaka-24 constituency when the former Dhaka District was split into six districts: Manikganj, Munshiganj, Dhaka, Gazipur, Narsingdi, and Narayanganj.
Nurul Majid Mahmud Humayun was re-elected unopposed in the 2014 general election after opposition parties withdrew their candidacies in a boycott of the election.
