Darimu is one of the 180 woredas in the Oromia Region of Ethiopia. This woreda takes its name from the name of the region it lies in, "Darimu", which is mentioned in Alexander Bulatovich's book, From Entotto to the River Baro, published in 1897. Part of the Illubabor Zone, Darimu is bordered on the south by Metu, on the west and north by the Kelem Welega Zone, and on the east by Supena Sodo.
