Dhaka-18 is a constituency represented in the Jatiya Sangsad (National Parliament) of Bangladesh. This constituency is currently represented by Bangladesh Nationalist Party candidate S M Jahangir Hossain.
The constituency encompasses Dhaka North City Corporation wards 1 and 17, and Dakshin Khan, Khilkhet, Turag, Uttara, and Uttar Khan thanas.
The constituency was created when, 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 added 7 new seats to the Dhaka metropolitan area, increasing the number of constituencies in the capital from 8 to 15.
