Economic growth of a country is determined by its ability to sustain the various development projects. Failure of the projects is, therefore, an indication of socio-economic stagnation as the nation lacks the capacity to provide the essential services and infrastructure. Kenya is seen as a critical player in the East Africa region with the country acting as a significant logistics and communications hub. The nation has made significant steps in growing its economy since independence through various development projects like Nairobi-to-Mombasa Standard Gauge Railway (SGR). Despite the efforts made towards improving the economy, Kenya is still associated with some of the most notable failed development projects. Challenges like poverty, insecurity and high unemployment are therefore persistent in the nation. This research aims to explore the reasons for the failure of development projects in Kenya. The study is designed to analyse information from primary sources to support the argument for the failure of development projects in the country. Some of the identified causes of lack of success in most projects include an absence of management capacity, cultural aspects, one size-fit-for-all, and accountability issues. The findings further indicate that corruption and dearth of participation of the beneficiaries are responsible for the failed projects in the country.
