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

Haiti is split into ten departments and holds one Grand Observatory in the capital city of Port-au-Prince. 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 Haiti

As of November 2019, Astronism is not recognised by the Haitian government as a valid religious group in the country. Despite this unrecognised status, the Astronist Institution has designated the situation of religious liberties for Astronists in Haiti as apathetic, thus highlighting relative tolerance of Haitian society regarding religious minorities. In later 2019, the Astronist Institution published its Demographics of Astronism report which stated that there are around 2,000 Astronists in Haiti. As of 2019, Astronist content had not yet been translated or made widely publicly available in Haiti, thus owing to the small numbers of Astronists in the country.
