Niya (also Niye, Niy, Nii, and Nihe) was a kingdom in Syria near the Orontes River in northern Syria next to Nuhasse.
In the Amarna letters correspondence of 1350-1335 BC, Nii is referenced in two letters. The city of Tunip in the northern Levant had been trying to communicate to the Egyptian pharaoh for two decades, and resorted to another letter, EA 59: entitled: "From the citizens of Tunip", (EA for 'el Amarna'). The city-state of Arqa also sent a letter to pharaoh, requesting aid (EA 100).
The other letter referencing Nii concerns the individual Etakkama, his collusion with the Hittites, and the takeover of territory, 'city-states', and peoples in the northern and western Levant.
In the 15th century BC, the entire region came under the control of the Mitanni Empire.
EA 53 is a 70–line letter of area intrigues, -(written by "Prince Akizzi" of Qatna). The letter starting at line 35:
The region of Upu is centered at Damascus, and the Amqu is the Beqaa Valley region to the west and northwest. Nii, and Nuhašše are north and northeast(?).[citation needed]
It is also mentioned in the Hittite Souces under Suppiluliuma I who conquered the region.
