Chakhansur (Balochi: چکانسور دمگ‎, Dari: ولسوالی چخانسور‎) is a district in the Nimruz Province of Afghanistan.

It has a population of about 11,165 as of 2004, which includes Baloch that form the majority followed by Tajik, and Pashtun ethnic groups.

This area of Afghanistan was a major medieval cultural hub on the Silk Road but most ancient structures are now covered by sand.

In 2004 the Chakhansur farmers had been experiencing a severe and long term drought.

Even with help from the World Food Program, perhaps as many as 20,000 have abandoned their homes, to search for water and jobs elsewhere.
