Krishan Nagar is part of the Islampura neighbourhood of Lahore, Punjab, Pakistan.

In the 1930s during British Raj, the development of middle class localities in Lahore started to change and areas like Krishan Nagar and Sant Nagar were established. They were planned as geometrical in layout and had parks, sewage and drinking water facilities. The houses of the rooms in these areas were high like British bungalows. These housing areas were an improved version of the old architecture of Lahore.

After the independence of Pakistan in 1947, the Hindu residents migrated to India. The area became mainly a residential quarter, heavily populated with Muslims. In 1992, after repeated protests from Muslims groups, Krishan Nagar and Sant Nagar were merged and renamed Islampura or 'Islam Town' to accurately reflect its demographic composition. However, it is still largely referred to by its former name similar to many other localities of Lahore such as Dharampura (renamed Mustafa-abad), Bhalla Stop (renamed Zaibunnisa stop).
