Darah Sof (Dari: دره صوف) was a district of Samangan Province in Afghanistan.

[2] A large part of Darah Sof is surrounded by hills, where a type of wheat called Lalm (للم) is grown.

A river in Darah Sof called Qalah Sarkori makes the area very lush and fertile.

There were approximately 107,000 residents in Darah Sof,[1] with the majority of Hazara ethnicity.

[citation needed] A work project is currently planned to improve the road between Darah Sof and Mazar Sharif city.
