Astro-Kenyan philosophy, or Kenyan Astronism, refers to the presence of Astronism in the Republic of Kenya under management and philosophical jurisdiction of The Institution of The Philosophy of Millettism for the Republic of Kenya, a national subsidiary for the worldwide Astronist Institution. The Institution of the Philosophy of Millettism for the Republic of Kenya oversees the construction and maintenance of observatories and planetariums throughout its jurisdiction.

Kenya is split into forty-seven counties and is set to hold two Grand Observatories in total in both the capital city of Nairobi, and in the city of Mombasa. This national branch of The Institution of The Philosophy of Millettism manages the official representation and depiction of Astronism throughout this territory, including efforts to protect the identity of the philosophy with the intention of further disseminating it throughout the territory. 

It is The Institution alone that is granted the status of proprietor to the philosophy in this territory as any other organisations or institutions proclaiming such a role are deemed as unauthorised proprietors and are therefore considered as part of the anti-Institutionist movement. 

History of Astronism in Kenya

Astronism is not currently recognised as a religion in Kenya as of November 2019 and in its latest Demographics of Astronism report, the Astronist Institution claimed 16,000 people in Kenya identified as Astronists. Kenya has become particularly important in relation to Astronism's presence in the East Africa subregion because Kenya is one of the only countries in which many citizens speak English. As of 2019, the majority of Astronist materials and content is produced in English so Kenyans are able to access and comprehend the full array of content relating to Astronism.
