Fateh Jang (Punjabi and Urdu: فتح جنگ) is a city in Attock District of Punjab Province, Pakistan. It is located 40 km (25 mi) from Attock City, and nearly 40 kilometres (25 miles) southwest of Islamabad, Pakistan's capital near M1 motorway.

The city is located in between Kala Chitta Range and Khairi Murat Range. The New Islamabad International Airport, the largest airport of Pakistan, is located near the city. Fatehjang railway station is one of the important railway stations in the Attock district. It is about 50KM away from Jund City which is the last tehsil of Attock District in Punjab after which the KPK Province starts.

According to local tradition, an ancient Hindu king named Raja Indra built a fort here, due to which this settlement came to be known as Indrakot, but its current name is attributed to an elder of the modern settlers here who fought many wars and always won. There is still a mosque of old times in the Mahallah Inderkot of the city. Its architecture suggests that the mosque is hundreds of years old and may have been built during Ghaznavid rule. This mosque is one of the archeological sites that have been protected under the country's law. During the Sikh period, the regional feudal lords remained the local rulers and paid tribute to the Sikh government. Fateh Jang came under British rule in 1848 after the region was conquered by the British Empire. Fateh Jang became a tehsil of Rawalpindi during British rule. Then in 1940, Attock District was formed and Fateh Jang was included in it. At that time, 203 villages were included in the tehsil Fateh Jang and it consisted of 1393 square kilometers. In 1891, the population of the tehsil was 113041 people. In February 1910, Fateh Jang was declared as notified area, while in January 1924, it got the status of a "small town Committee".
