Ndeiya is located in Kiambu County, Kenya, and is near the Great Rift Valley. The name is derived from a Maasai word.
The region stretches nearly 55 kilometres (34 mi) from the lower Ngong hills area ("Kibiku") to the Mutarakwa Mai Mahiu road, and falls under the Kikuyu/Kabete and Limuru constituencies. The area adjacent to Maasai plain is quite scenic with undulating hills and valleys. It is a famous rock climbing venue.
Some areas in Ndeiya region include Gikambura, Ruthigiti, Kamangu, Kianjagi, Migumoini, Kanyayo, Ng'amba, Renguti, Karabuta, Gatune, Rwanyaga, Nachu, Nguirobi, Gitutha, Nduthi, Kiriri, Kiawanda, Thigio,Githarane, Mung'etho, Nderu, Mirithu, Tiekunu, Kiandutu and Githunguchu
Ndeiya lies on the border between the territories of the Kikuyu and Maasai people. Research shows that many people in Ndeiya have some Maasai blood, as the two communities had some close links. Ndeiya people are mostly those of Kikuyu origin' but other tribes and races can be found there.

A unique settlement feature in Ndeiya is the existence of the Emergency Villages that were established under colonial rule in 1950s. The village include Ndioni, Nderu (Royal),Mung'etho,Thigio, and Ruthigiti. The residents of the villages are landless and not endowed with significant means of gainful employment. Consequently Ndeiya isnot food secure.
The region has many schools, among them primary and secondary schools. Several boreholes have been sunk, and clean water for domestic consumption is adequate. Fluorine content of the water is high, and there is a prevalence of dental fluorosis in the area.
Supply of electricity is good, with most trading centres connected to the National Grid. The main road to Ndeiya can be accessed from Kikuyu and Limuru.There is also a route from Ngong hills and Dagoretti. Much of Ndeiya is semi-arid, and is therefore considered a hardship area. Before the collapse of the pyrethrum industry in Kenya, pyrethrum was a major cash crop in Ndeiya. Poultry farming has been carried out, though not to a large scale. Subsistence farmin is common and the unemployment level is high.
