The Amaro Mountains are a mountain range in south western Ethiopia. Extending 60 kilometers along a north–south axis east of Lake Chamo, these mountains are located in the Nechisar National Park, which lies in the Amaro special woreda. These elevations expose an assemblage of uniform, fine-grained, holocrystalline olivine-basalts with local tuff bands, resting upon the basement complex. It is uncertain whether these mountains are a remnant plateau now looking down on the grabens to either side (the and ), or if these mountains were squeezed up from the basement of the East African Rift, possibly by processes similar to those that formed the Ruwenzori Mountains.
