Astro-Colombian philosophy, or Colombian Astronism, refers to the presence of Astronism in the Republic of Colombia under management and philosophical jurisdiction of The Institution of the Philosophy of Millettism for the Republic of Colombia, a national subsidiary for the worldwide Astronist Institution. 

The Institution of the Philosophy of Millettism for the Republic of Colombia oversees the construction and maintenance of observatories and planetariums throughout its jurisdiction. Colombia is split into thirty-two departments and one capital district, and is set to hold one Grand Observatory in the capital city of Bogotá. 

History of Astronism in Colombia

As of November 2019, Astronism is not recognised as a religion by the government in Colombia. Despite this, the Colombian government has a positive track record with regards to respecting religious freedoms and hence, Astronists are considered to be free to publicly profess their faith without significant concerns of repression or ostracism. 

The number of Astronists in Colombia has been estimated by data sources from within the Astronist Institution at 3,000 people. Spanish content for Astronists is still in production by Astronism.org publisher as of late 2019, but until such content is published, Colombian Astronists will remain restricted in the extent of the content they can access and comprehend.
