Nilphamari-3 is a constituency represented in the Jatiya Sangsad (National Parliament) of Bangladesh. Obaidullah Salafi is the current member of Parliament.
The constituency encompasses Jaldhaka Upazila.
The constituency was created in 1984 from a Rangpur constituency when the former Rangpur District was split into five districts: Nilphamari, Lalmonirhat, Rangpur, Kurigram, and Gaibandha.
Ahead of the 2018 general election, the Election Commission altered the boundaries of the constituency. Previously it included three union parishads of Kishoreganj Upazila: Barabhita, Putimari, and Ranachandi.
