Oroks (Oroki in Russian; self-designation: ulta, ulta, ulcha) are a people in the Sakhalin Oblast (mainly the eastern part of the island) in Russia. The Orok language belongs to the Southern group of the Tungusic language family and is unwritten. According to the 2002 Russian census, there were 346 Oroks living in Northern Sakhalin by the Okhotsk Sea and Southern Sakhalin in the district by the city of Poronaysk. The name Orok is believed to derive from the exonym Oro given by a Tungusic group meaning "a domestic reindeer". The Orok self-designation endonym is Ul'ta, probably from the root Ula (meaning "domestic reindeer" in Orok). Another self-designation is Nani. Occasionally, the Oroks, as well as the Orochs and Udege, are erroneously called Orochons. The Russian Empire gained complete control over Orok lands after the 1858 Treaty of Aigun and 1860 Convention of Peking.
