Gera Midirna Keya Gebriel ("Gera Midir and Keya Gebriel") was one of the 105 woredas in the Amhara Region of Ethiopia. It is partly named after the northern district of the former province of Menz, Gera Meder. Located at the eastern edge of the Ethiopian highlands in the Semien Shewa Zone, Gera Midira Keya Gebriel was bordered on the south by Mam Midrina Lalo Midir, on the southwest by the Jamma River which separated it from Moretna Jiru, on the northwest by the Qechene River which separates it from the Debub Wollo Zone, on the north by Gishe, and on the east by the Oromia Zone. The administrative center of this woreda was Mehal Meda; other towns include Zemero. It was divided for Menz Gera Midir and Menz Keya Gebreal woredas.
Elevations in Gera Midirna Keya Gebriel range between 1000 and 4000 meters above sea level. The highest point in this woreda, as well as the Zone, is Mount Abuye Meda (4012 meters) near the eastern border.
