Niksar is a district of Tokat Province, located in the Black Sea Region. The district's economy is based on agriculture and forestry products. Historical structures and natural areas are located within the district.

History
Niksar is situated on the slopes of the northwest of the Kelkit Valley. During the Pontic Kingdom, the settlement was called "Kaberia (Cabira). It was named "Diospolis" and "Sebaste" in the Roman period, and was renamed "Neocaesarea" in memory of Emperor Tiberius (14–17 AD). The current name "Niksar" is derived from a shortened form of Neocaesarea. Niksar Castle was built during the Hellenistic period as an acropolis and was surrounded by three layers of walls during the Roman period. During the Byzantine period, two bathhouses, two small mosques, a church, a madrasah, and a prison were added to the castle; the remains of these structures can still be seen today.
Following the 1071 Battle of Manzikert, the Danishmend Gazi Melik Ahmet Gazi entered the region, capturing Niksar in 1083–1084 and making it one of the centers of the Danishmend Principality. Built by Cepnizade Hasan Bey in the early 12th century, the Ulu Mosque (1145) with its rectangular plan and five-nave structure is among the earliest examples of mosques in Anatolia. Following the Danishmends, the region was ruled by the Ilkhanate, Eretna, and Kadı Burhaneddin; it was annexed to the Ottoman Empire in 1392. Niksar remained outside the Ottoman Empire for a short time after the Battle of Ankara (1402), but was re-incorporated into Ottoman rule in 1413. In 1461, Mehmed the Conqueror visited the region and performed the Eid prayer at the Ulu Mosque. Niksar, a district of the Tokat Sanjak during the Ottoman period, gained district status within the province of Tokat under the Republican administration in 1924.

In the agricultural sector, grain, vegetable, and fruit (especially apple and viticulture) production, along with livestock farming, are carried out in the fertile lands of the Kelkit Plain.
