Olymp-K (Russian: Олимп-К meaning Olympus) was a Russian geostationary satellite built for the Russian Ministry of Defence and Federal Security Service (FSB). The satellite was also referred to at times as "Luch" (Russian: Луч; lit. Ray, Beam) even though it was not a Luch satellite. The Olymp-K satellite also sometimes went by the name "Olymp-1" (or just "Olymp") and it was assigned code "Kosmos 2501" at one point, before the name Kosmos 2501 was given to an other satellite (a GLONASS satellite). It was believed to be a signals intelligence satellite.
