Lay Armachiho (Amharic: ላይ አርማጭሆ|lāy ārmāčihō|lit=Upper Armachiho) is a woreda in Amhara Region, Ethiopia. This woreda is named after "Armachiho", a province in northwestern Ethiopia along the border with Sudan and south of the Tekezé River.[3] Part of the Semien Gondar Zone, Lay Armachiho is bordered on the south by Dembiya, on the west by Chilga, on the north by Tach Armachiho, on the east by Wegera, and on the southeast by Gondar Zuria. The administrative center of this woreda is Tekle Dingay.
Lay Armachiho was selected by the Ministry of Agriculture and Rural Development as an area for voluntary resettlement for farmers from overpopulated areas in the fourth round of resettlement program. Along with Qwara and Dangila in the Amhara Region, and Tsegede in the Tigray Region, this woreda became the new home for 8,671 families.[4] This round of resettlement was reportedly accompanied with almost 68 million Birr in infrastructure development.[5]
Based on the 2007 national census conducted by the Central Statistical Agency of Ethiopia (CSA), this woreda has a total population of 157,836, an increase of 34.36% over the 1994 census, of whom 79,538 are men and 78,298 women; 12,546 or 7.95% are urban inhabitants. With an area of 1,059.33 square kilometers, Lay Armachiho has a population density of 149.00, which is greater than the Zone average of 63.76 persons per square kilometer.

The majority of the inhabitants practiced Ethiopian Orthodox Christianity, with 97.9% reporting that as their religion, while 2% of the population said they were Muslim.[6] The Qemant, one of the Agaw people, are the largest ethnic group living in this woreda, and are concentrated around the town of Tekle Dingay. The head priest in Tekle Dingay has more prestige than his counterpart in Chilga woreda, because he rules their traditional homeland.[7]
