The Carlsberg Meridian Telescope (formerly the Carlsberg Automatic Meridian Circle) is a decommissioned meridian circle telescope located at the Roque de los Muchachos Observatory in the Canary Islands. It was dedicated to high-precision optical astrometry and operated from May 1984 to September 2013.

The CMT's 20 years of photometric data was studied to understand atmosphere extinction. Up to 2003, 11 catalogs were published and it had been given various upgrades since its installation in 1984.
