Yeki is a woreda in South West Ethiopia Peoples' Region, Ethiopia. Part of the Sheka Zone, Yeki is bordered on the south by the Bench Maji Zone, on the west by the Gambela Region, on the north by Amderacha, and on the east by the Keffa Zone.The name 'Yeki' is named after the name of Sheko chief. The major town in Yeki is Tepi. Tepi is also named after the name of Majang man who live in the center of the current Tepi town.

The highest point in Yeki is Mount Teppi (2728 meters), a dormant volcano. Major rivers include the Beko and Shiy. Two varieties of subsistence agriculture are practiced in this woreda: one, in the northwestern corner, is based on growing cereals and enset; the other, in the rest of the woreda, is based on coffee and spices. Important cash crops in the first part include corn, teff, wheat, pulses, and enset; while in the second they are corn, sorghum, coffee, ginger and turmeric. Other important non-agricultural sources of income include selling milk. According to a 2004 report, Yeki had 76 kilometers of all-weather roads, for an average road density of 126 kilometers per 1000 square kilometers.

A 2002 United Nations Emergency Unit for Ethiopia assessment report mentions increasing conflict between the Majang and Sheko, which spilled over into neighboring Godere of the Gambela Region. The Majang and Sheko people claimed the ownership of the Yeki Woreda and they demanded to be granted political self-administration.
