Okno (Russian: Окно literally "window", stands for "Оптический контроль небесной области", "Optical control of the celestial region") is a Russian space surveillance station located in Tajikistan. It is run by the Russian Space Forces and is part of the Centre for Outer Space Monitoring. It is located 2,216 metres (7,270 ft) above sea level on the Sanglok mountain in Pamirs, an area with clear night skies. Its personnel is stationed in Norak. It is also known as Оптико-электронный комплекс "Нурек".

The facility consists of a number of telescopes in domes and is similar to the US GEODSS system. It is designed for the detection and analysis of space objects such as satellites. The designers were awarded a Russian state prize for science and technology in 2004.
