Sylhet-2 is a constituency represented in the Jatiya Sangsad (National Parliament) of Bangladesh. Tahsina Rushdir Luna is the incumbent representative since February 2026.
The constituency encompasses Bishwanath and Osmani Nagar upazilas, 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.
Ahead of the 2018 general election, the Election Commission altered the boundaries of the constituency. Previously it included three union parishads of Balaganj Upazila: Dewan Bazar, Paschim Gauripur, and Purba Gauripur, but did not include Osmani Nagar Upazila.
