Astro-Jamaican philosophy, or Jamaican Astronism refers to the presence of Astronism in Jamaica under management and philosophical jurisdiction of The Institution of The Philosophy of Millettism for Jamaica, a national subsidiary for the worldwide Astronist Institution. The Institution of the Philosophy of Millettism for Jamaica oversees the construction and maintenance of observatories and planetariums throughout its jurisdiction. Jamaica is split into fourteen parishes and is set to hold one Grand Observatory in the capital city of Kingston. 

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.
