Guwahati Planetarium, Planetarium and astronomy center in Guwahati, India.

Guwahati Planetarium is an astronomy education center located in Guwahati, the largest city in Assam, northeastern India. It features a domed theater for sky shows, equipped with a Chronos star field projector combined with digital HD video projectors.

The planetarium was established on 17 August 1994, making it the oldest planetarium in Assam and Northeast India. It is run by the Assam government's Department of Science and Technology. It was the second facility in India, after New Delhi's Nehru Planetarium, to receive a hybrid planetarium projection system, the first of its kind in the northeast.

Shows are presented in both Assamese and English, so visitors from the region and from abroad can follow along without difficulty. The programs are shaped to welcome anyone curious about the night sky, regardless of prior knowledge.

The center holds regular sky watching sessions where staff guide visitors through telescopes to observe objects in the night sky. Visiting outside the monsoon season generally gives clearer skies for observation.

The hybrid projection system was the first of its kind in Northeast India and only the second in the country, after the Nehru Planetarium in New Delhi. Japanese software firm Goto supplied the planetarium's software. Models of a Polar Satellite Launch Vehicle and an Indian Remote Sensing satellite are on display inside.
