Mantare is one of 18 wards of the Kwimba District of the Mwanza Region in Tanzania. It is located at 33° 13' E, 2° 42' S. Like many of its neighboring wards, Mantare is inhabited by the Wasukuma people who speak Kisukuma and Swahili, the national language of Tanzania.
The landscape is quite rural, and much of the farmland is used for growing rice, corn, cassava, and cotton. Most of the inhabitants are subsistence farmers, though a few work in the institutions found in the nearby village of Sumve.
