Ruiru is a municipality and sub-county in Kiambu County, Kenya. It sits within the greater Nairobi Metropolitan region. According to the 2019 national population census, Ruiru is the 4th largest urban centre in Kenya by population.[1][2] The name Ruiru is of the Kikuyu dialect and possibly relates to the black cotton soil that is found in most parts of Ruiru to the east and south.[3]
