Rajbari-1 is a constituency represented in the Jatiya Sangsad (National Parliament) of Bangladesh since 2008 by Kazi Keramat Ali of the Awami League.
The constituency encompasses Goalanda and Rajbari Sadar upazilas.
The constituency was created in 1984 from a Faridpur constituency when the former Faridpur District was split into five districts: Rajbari, Faridpur, Gopalganj, Madaripur, and Shariatpur.
Kazi Keramat Ali was re-elected unopposed in the 2014 general election after opposition parties withdrew their candidacies in a boycott of the election.
Md. Abdul Wajed Chowdhury died in office. Kazi Keramat Ali was elected in an October 1992 by-election.
