Mjini and Vijijini: urban and rural districts

Most district names are the same in Swahili and English. Where a town and its countryside form two districts, Swahili adds Mjini, urban, or Vijijini, rural, and English translates: Dodoma Mjini is Dodoma Urban, Bukoba Vijijini is Bukoba Rural. Both are administered from the town itself, so the seat column repeats its name.

A name in the seat column means the district is run from another place. Arumeru is governed from Akheri, Kilolo from Ilula, Makete from Iwawa and Mufindi from Mafinga; in Kilimanjaro Region, Rombo has its seat at Tarakea Motamburu.

The district list follows 26 regions. Since then Tanzania has added five: Geita, Katavi, Njombe and Simiyu in 2012, and Songwe, carved from the western part of Mbeya Region, in 2016. The districts that carry the names of their capitals stand here under older regions: Geita under Mwanza, Mpanda under Rukwa, Njombe under Iringa, Bariadi under Shinyanga, and Mbozi, governed from Vwawa, under Mbeya.

Wikipedia, in its table of the regions read on 28 October 2026, counts between two and eleven districts per region, from the Zanzibar regions to Tanga. The district counts in the table above are those of this list, not the current ones.
