Manikganj-3 is a constituency represented in the Jatiya Sangsad (National Parliament) of Bangladesh.

The constituency encompasses Saturia Upazila and all but the three southernmost union parishads of Manikganj Sadar Upazila: Bhararia, Hati Para, and Putail.

[2][3] The constituency was created in 1984 from the Dhaka-3 constituency when the former Dhaka District was split into six districts: Manikganj, Munshiganj, Dhaka, Gazipur, Narsingdi, and Narayanganj.

Ahead of the 2008 general election, the Election Commission redrew constituency boundaries to reflect population changes revealed by the 2001 Bangladesh census.

Abdul Wahab Khan of the BNP was elected in a 1996 by-election.
