Chapai Nawabganj-1 is a constituency represented in the Jatiya Sangsad (National Parliament) of Bangladesh. Since 6 August 2024 the constituency is vacant.
The constituency encompasses Shibganj Upazila.
The constituency was created in 1984 from the Rajshahi-1 constituency when the former Rajshahi District was split into four districts: Nawabganj, Naogaon, Rajshahi, and Natore.
Golam Rabbani was elected unopposed in the 2014 general election after opposition parties withdrew their candidacies in a boycott of the election.
