The constituency was created for the first general elections in newly independent Bangladesh, held in 1973.
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. Thus Chittagong-15 covers the area previously covered by Chittagong-14. Previously Chittagong-15 encompassed Banshkhali Upazila.[2][3]
