# Chittagong-13

Chittagong-13 is a constituency represented in the Jatiya Sangsad (National Parliament) of Bangladesh. Since 6 August 2024 the constituency is Vacant.

## Boundaries

The constituency encompasses Karnaphuli Thana, Anwara Upazila, and five union parishads of Patiya Upazila: Bara Uthan, Char Lakshya, Char Patharghata, Juldha, and Sikalbaha.

## History

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. Thus Chittagong-13 covers the area previously covered by Chittagong-12. Previously Chittagong-13 encompassed Chandanaish Upazila and seven union parishads of Satkania Upazila: Bazalia, Dharmapur, Kaliais, Keochia, Khagaria, Puranagar, and Sadaha.
