Saddar Town (Urdu: صدر ٹاؤن), lies in the south part of the city that formed much of the historic colonial core of Karachi.

The word Saddar generally means the "center" (of a settlement) and also the "head" (of a group of people or an organisation). The word Saddar may loosely be translated into "Downtown" as it shares common characteristics with a Downtown of any particular city located in United States. This includes historic areas, attractions, being in the center etc.

Saddar Town is located in the colonial heart of Karachi. It is bordered by Jamshed Town and Clifton Cantonment to the east, Kiamari Town and the Arabian Sea to the south and Lyari Town to the west. The majority of the population are Muhajirs of Gujarati origin. Among the Gujarati-speaking people are trading communities such as Memons and Marwaris.^[3]

Saddar Town contained much of the oldest parts of Karachi. The federal government under Pervez Musharraf, introduced local government reforms in the year 2000, which eliminated the previous "third tier of government" (administrative divisions) and replaced it with the fourth tier (districts). The effect in Karachi was the dissolution of the former Karachi Division, and the merging of its five districts to form a new Karachi City-District with eighteen autonomous constituent towns including Saddar Town as part of The Local Government Ordinance 2001, and was subdivided into 13 union councils. In 2011, the system was disbanded but remained in place for bureaucratic administration until 2015, when the Karachi Metropolitan Corporation system was reintroduced.^[4]

In 2015, Saddar Town was re-organized as part of Karachi South.

In January 2022, the town system was restored by a Government of Sindh notification dividing Karachi South District into 2 towns including Saddar Town having 13 union councils.^[5]

Saddar Town was made up of the following:

• Saddar
• Karachi
• Darya Lal Mandir
