Sylhet-1 is a constituency represented in the Jatiya Sangsad (National Parliament) of Bangladesh. Khandaker Abdul Muktadir is the incumbent representative since February 2026.
The constituency encompasses wards 1 through 27 and 31 through 39 of Sylhet City Corporation, along with Sylhet Sadar Upazila, integrating these areas within a single administrative and electoral boundary.
The constituency was created for the first general elections in newly independent Bangladesh, held in 1973.
Ahead of the 2008 general election, the Election Commission redrew constituency boundaries to reflect population changes revealed by the 2001 Bangladesh census. The 2008 redistricting altered the boundaries of the constituency.
Abul Maal Abdul Muhith was re-elected unopposed in the 2014 general election after opposition parties withdrew their candidacies in a boycott of the election.
