Nyahururu is a town in Kenya, lying east of Nakuru. It is part of Laikipia District in the Rift Valley Province. Despite this, Nyahururu formerly functioned as the administrative capital of Nyandarua District, one of seven districts that constitute the Central Province in Kenya, until the headquarters was shifted to Ol Kalou. Nyahururu was founded as Thomson Falls after the 70 metre high Thomson's Falls on the nearby Ewaso Nyiro River, which drains from the Aberdare mountain ranges. It is on the Junction of Nyeri-Rumuruti road and the Nyeri-Nakuru road.
The town grew around a railway from Gilgil opened in 1929 (now effectively abandoned). The town was once an important player in the timber milling industry, and the now defunct National Pencil Company had a factory there. It is also an important milk processing hub. Egerton University's Laikipia campus is on the outskirts of Nyahururu town. With high quality education offered by private schools, most children from this area have gone on to lead successful lives. The region around Nyahururu is mainly agricultural. To the North Ol Ngarua is famous for its maize, while Shamata to the south is a major producer of potatoes. Lately, flower farming has brought new life to Nyahururu. Suera Flowers is a pioneer in this venture. The cool temperate weather, land availability and cheap labor may be some of the important contributors to flower farming.
