Karoi is a town located in Mashonaland West Province.
The Karoi Local Government is Karoi Town Council.
The name is derived from the River Karoyi. Muroyi is ChiShona for witch. The prefix ka is a diminutive. Hence, little witch. Witches and other sorcerers were thrown into the river, and the bodies flowed down into the Angwa River. Another story is that this river, though small, is particularly dangerous (treacherous, wayward, withch-like) when in flood. 
It is home to about 25,030 people and the population comprises of both sexes of different nationalities although the majority are local Zimbabweans.
Court interpreter and reporter, then journalist Charles Laiton went to school in Karoi.
