Asadabad (), also called Chaghasarai (), is the capital city of Kunar Province in Afghanistan. It is located in the eastern-northeastern portion of the country. The city is located within a valley at the confluence of the Pech River and Kunar River between two mountain ridgelines running along both sides of the valley from Northeast to Southwest. Asadabad is in a mountainous region of the Hindu Kush mountains about 13 km (eight miles) northwest of the Pakistani border and 80 km (50 miles) northeast of Jalalabad, Afghanistan. Asadabad deals with a moderate amount of trade goods. Nawa Pass, that lies about 16 km (10 miles) south of Asadabad, is the next major border crossing point north of the Khyber Pass for the region. The pass is under constant observation due to its relative ease to cross for commerce and its potential usage for smuggling and Taliban insurgents. On 14 August 2021, Asadabad was seized by Taliban fighters, becoming the twenty-first provincial capital to be captured by the Taliban as part of the wider 2021 Taliban offensive.

In the past, the area near Asadabad was called "Chagha Sarai", with various spellings (Chaga Serai, Chagasaray, Chigur Serai, Chughansuraee). Emperor Babur (late 15th century/early 16th century) claims to have taken over the town as part of his military campaigns in the area. He describes it very briefly in his book, Baburnama. He also mentions relations with the Kaffirs, whom he claims helped defend the town against him. In the late 19th century/early 20th century the capital of the region was moved from Pushoot/Pasat/Pasad to the present Asadabad location.
