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

Ghana is split into ten administrative regions and holds one Grand Observatory in the capital city of Accra. 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 Ghana

Astronism is not recognised as a valid religious group in Ghana and as of November 2019, the number of Astronists in the country was estimated at just 1,000. Astronist religious liberties in Ghana have been designated as apathetic in the 2020 Astronist Freedom report highlighting the relative tolerance towards religious minorities of the Ghanaian government. English is widely spoken in the country which acts as a significant furtherer of the Astronist religion in the country with the majority of content about Astronism being written in English by late 2019.
