Shirin-Tagab (meaning in Uzbek language: "Sweet Water", also known as Koh-i-Saiyād) is the district center in the Faryab Province, Afghanistan.

The valley of Shirin-Tagab hosts many villages with a central township comprising two hundred shops.

The Shirin-Tagab road in a point, which is 20 km from Maymana, branches off the river's stream valley.

Livestock and grain are the main items of transactions in the bazaar before the war.

Because most of the central and northern districts in Faryab Province have a salty water supply from the Shirin Tagab River, many civilians bring water from the Shirin Tagab bazaar.
