Kaffa was a province on the southwestern side of Ethiopia; its capital city was Jimma. It was named after the former Kingdom of Kaffa. The etymology of Kaffa is thought to be from the Arabic qahwah meaning "a drink from berries". The English word coffee is derived from the same root. Kaffa was bordered on the west by Sudan, on the northwest by Illubabor, on the north by Walega, on the northeast by Shewa, on the east by Sidamo, and on the southeast by Gamu-Gofa. For the former province, see Keffa Province. Keffa is a Zone in the Ethiopian Southern Nations, Nationalities, and Peoples' Region. Keffa is bordered on the south byDebub Omo, on the southwest by Bench Maji, on the west by Sheka, on the north by the Oromia Region, and on the east by Konta. Gojeb River runs along part of the northern border of this zone. The administrative center of Keffa is Bonga. Keffa formed the main part of former Keficho Shekicho Zone.

Economy and environment
Southern Ethiopia, including Sidamo, Kaffa, Arsi and Harar is the original home of coffee which grows wild here in the mountain rain forests in countless varieties. All plants of the species Coffea arabicaaround the world are descendants of plants from southern Ethiopia. Coffee has long been the main source of income, but due to the sharply declining world prices for coffee, the residents increasingly have to grow other crops. By turning rain forests into new agricultural land, the structure of the region is heavily damaged. The rain forests that dominated the region of Kaffa earlier are reduced to only 3% of their original size, in the last 30 years 60% of the trees were lost. For some years there is a large rain forest conservation project, which relies on the use of the last wild stocks of coffee growing in the rain forest. Currently, some 30 cooperatives are harvesting and marketing this specialty coffee and have helped over 40,000 people to get income. In 2010, an area within the Kaffa province was recognised as a UNESCO Biosphere Reserve as part of the Man and the Biosphere Programme. Officially named the "Kafa Biosphere Reserve" it is one of the first two biosphere reserves in Ethiopia and aims to protect the natural environment and foster sustainable development in the region. Lions were photographed in the reserve in 2012, the first documenting of that species in montane rainforest.
