Alfa Planetarium (Spanish: Planetario Alfa) was a planetarium located in Monterrey, Nuevo León, Mexico. This institution was created by ALFA (Mexico) in 1978 to promote science and technology in Latin America. It included an interactive science museum, an Omnimax system cinema, an aviary and an area for temporary exhibits and events. The Alfa Planetarium was one of the most visited cultural centers in Mexico. While its main focus was on science, it also had some art pieces.^[1]

It was closed definitively on the 4th of September 2020, after 42 years of operation. The main reasons behind the decision were the lack of investment in upgrades required due to rapidly advancing technology, a reduction in revenue due to sanitary measures implemented during the COVID-19 pandemic, and a lack of public investment in cultural projects.^[2] It is thought to have had over 15.2 million visitors during its entire run.^[3] By the end of its life, it had over 500 pieces in its permanent exhibitions.^[1]

It was inaugurated in October 1978, under its initial name of "Centro Cultural Alfa" translating to Alfa Cultural Center. At its inauguration the then Secretary of Education, Fernando Solana Morales, and the then president of the ALFA Group Bernardo Garza Sada were present. It was a revolutionary museum, in many ways, for Mexico and Latin America. For example, its Mega Screen IMAX Dome was the first to begin operating outside the United States in the continent.^[1]

Personalities such as the Mexican Nobel Literature Prize winner Octavio Paz, and the astronaut Rodolfo Neri Vela, stand out among the most relevant visitors to the Alfa Planetarium. In 2014 it was also visited by King Charles III, and by his wife Queen Camilla, where they met with the top companies of Nuevo Leon, and the Secretary of Economy.^[1]

On April 19, 2023, most of its former attractions were relocated and unveiled at the newly-inaugurated Museo Universitario de Ciencias, located on the right corner of the Preparatoria 3 of the UANL.^[4]
