Mpwapwa District is one of the seven districts of the Dodoma Region of Tanzania. It is bordered to the north by Kongwa District, to the east by Morogoro Region, to the south by Iringa Region, and to the west by Chamwino District. Its district capital is the town of Mpwapwa.

Most Mpwapwa residents live on the central plateau at about 3,500 ft (ca. 1,067 m) above sea level, though others, mainly from the minority Hehe ethnic group, live atop the 7,000 ft (ca. 2,134 m) mountains that benefit from better rainfall. The district is fairly arid and only gets good rains 2 years out of every 7.

Paved trunk road T5 from Dodoma to Iringa passes through the southern part of the district.

The central railway of Tanzania passes through Mpwapwa District as well, with one station being located in Gulwe.

As of 2012, Mpwapwa District is administratively divided into 30 wards.

'Almandine-Pyrope Series'Locality: Winza, Mpwapwa District, Dodoma Region, TanzaniaReferences: King, Van (n.d.) Personal communcation.
CorundumFormula: Al2O3Locality: Winza, Mpwapwa District, Dodoma Region, TanzaniaHabit: occur in a range of crystal shapes; prismatic-tabular-rhombohedral and dipyramidalColour: orange, pink, red, purple and blue. Often zoned. Description: Corumdum is found in eluvial sediments rarely exceeded a cm, the corundum found in the amphibolite dykes can be significantly larger, crystals approaching 10 cm has been found. The Winza corundum can occur in a range of crystal shapes; prismatic-tabular-rhombohedral and dipyramidal. In general, medium red and dark (orangy) red top-quality rubies are rhombohedral. Pinkish red and purplish red rubies, as well as pink, purple, and blue (often strongly color zoned) sapphires are, for the most part, dipyramidal Some of the rhombohedral crystals resemble spinel octahedral, but the angles between the crystal faces are different, and twin lines are common.References: Schmetzer, K., Radl, W. & Schwarz, D.
