Chittagong-7 is a constituency represented in the Jatiya Sangsad (National Parliament) of Bangladesh. Since 6 August 2024 the constituency is Vacant.
The constituency encompasses Rangunia Upazila and one union parishad of Boalkhali Upazila: Sreepur Kharandwip.
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 2014 general election, the Election Commission renumbered the seat for Sandwip Upazila from Chittagong-16 to Chittagong-3, bumping up by one the suffix of the former constituency of that name and the higher numbered constituencies in the district. Prior to that, Chittagong-7 had encompassed all but one union parishad (Sreepur Kharandwip) of Boalkhali Upazila, and Chittagong City Corporation wards 3 through 7.
