Jor is one of the woredas in the Gambela Region of Ethiopia. Part of the Anuak Zone, Jor is bordered on the south by the Akobo River which separates it from South Sudan, on the west and north by the Nuer Zone, on the northeast by Abobo, and on the east by Gog; the Alwero River defines part of its northern boundary. The administrative center of this woreda is Ongogi.
The terrain of Jor is flat, and the eastern part is swampy; the elevation ranges from 300 to 400 meters above sea level. Important rivers in this woreda include the Gilo. According to the Atlas of the Ethiopian Rural Economy published by the Central Statistical Agency (CSA), around 15% of the woreda is forest. A notable landmark is the Gambela National Park, which occupies the woreda north of the Gilo.
The economy of Jor is predominantly agricultural. There are no agricultural cooperatives, no documented roads, and little other infrastructure.
At the start of the Federal Democratic Republic of Ethiopia, Jor was part of the Administrative Zone 2; however between 2001 and 2007 the Zone was reorganized and Jor became part of the Anuak Zone.
On 11 April 2007, it was reported that over 1,000 well-armed members of the Murle crossed from southern Sudan and attacked an Anuak village named Angela in Jor, some 150 kilometers from the capital, Gambela. The attack claimed the lives of 26 people, left 13 people seriously wounded, 200 houses burnt, and large herds of cattle stolen. This raid was preceded by one on a Nuer village, called Bilimkuon, 95 kilometers from the capital; this attack left seven people dead, and rustled over 3,936 head of cattle.
