Tanzania is divided into 31 regions, which are further divided into districts. Here is a list of the 31 regions of Tanzania as of my knowledge cutoff in September 2021:
Tanzania is a country in East Africa bordered by Kenya, Uganda, Rwanda, Burundi, the Democratic Republic of the Congo, Zambia, Malawi, Mozambique, and the Indian Ocean. The country is divided into 31 regions for administration and governance, including regions on the mainland and the semi-autonomous islands of Zanzibar. Dodoma is the official capital of Tanzania, while Dar es Salaam remains the country’s largest city and main commercial center.
Tanzania includes coastal plains, savannas, mountains, lakes, forests, and parts of the Great Rift Valley spread across a large and diverse landscape. Different regions are known for tourism, mining, agriculture, fishing, trade, wildlife conservation, and industry, and the country is home to famous places like Mount Kilimanjaro, Serengeti National Park, and the Zanzibar archipelago.
