Astro-Eritrean philosophy, or Eritrean Astronism, refers to the presence of Astronism in Eritrea. This country is under management and philosophical jurisdiction of The Institution of The Philosophy of Millettism for the State of Eritrea, a national subsidiary for the worldwide Astronist Institution. The Institution of the Philosophy of Millettism for the State of Eritrea oversees the construction and maintenance of observatories and planetariums throughout its jurisdiction. 

Eritrea is split into six administrative regions and is set to hold one Grand Observatory in the capital city of Asmara, which will also be one of only two observatories in the nation. 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 Eritrea

Religious liberties for Astronists in Eritrea remain particularly dismal. This is due in part to the unrecognised status of Astronism as a religion in the country and the widespread violations of religious freedom laws in Eritrea. For this reason, in its 2020 Astronist Freedom report, the Astronist Institution has designated the situation for Astronist religious liberties in Eritrea as terminal. 

The number of Astronists in Eritrea has been calculated at just 50 people as of November 2019. This is due in part to the severe oppression faced by religious minorities in the country as well as due to the significant media censorship applied throughout the country which is particularly focused on censoring all non-Islamic and non-Christian religious content.
