Nannawa Adama (Oromo: Naannawa Adaamaa; Amharic: አዳማ ዙሪያ ) is a woreda in Oromia Region, Ethiopia. Part of the East Shewa Zone located in the Great Rift Valley, Adama Zuria is bordered on the south by the Arsi Zone, on the southwest by Koka Reservoir which separates it from Dugda Bora, on the west by Lome, on the north by the Amhara Region, and on the east by Boset; the Awash River, the only important river in this woreda, defines the woreda boundaries on the east and south.

Fruits, vegetables and sugar cane are important cash crops.^[1]

Adama Zuria has a severe invasive species problem with Eichhornia crassipes, the water hyacinth. Locals believed the weed was introduced to the woreda through the 1996 flood of the Awash, which brought plants from the Koka Reservoir into both residential areas and the Wonji Sugar Plantation, where it has infested 116.4 hectares of irrigation structures, causing water loss, increased labor, and providing an environment that encourages malaria-carrying mosquitos and schistosomiasis.^[2]
