Qasimabad (Sindhi: قاسم آباد) is a town/city in the western side of Hyderabad City in Sindh province of Pakistan.

It was formed as an extension to the city of Hyderabad after the arrival of migrants from across the border after the 1947 independence of Pakistan, along with the town of Latifabad.

The locals that lived in the town at its inception were ethnically of a mixed population but as the city experienced ethnic riots between Sindhis and Muhajir in the late 1980s.

Widespread target killings and acts of ethnic cleansing were committed, the city got divided between the Sindhis and Muhajir with the former mainly settling in Qasimabad while the latter settling in Latifabad.

Qasimabad is the hub of Sindhi Nationalist and political Powers and almost all the Sindhi Nationalist political parties have their head offices in Qasimabad City.
