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.[1]

The CMT's 20 years of photometric data was studied to understand atmosphere extinction.[2] Up to 2003, 11 catalogs were published and it had been given various upgrades since its installation in 1984.[3]

The telescope is owned by the Danish Copenhagen University Observatory and was jointly operated under an international agreement with the Institute of Astronomy, Cambridge and the Real Instituto y Observatorio de la Armada.[3]
