In the fictional Star Trek universe the Klingon High Council (in Klingon tlhIngan yejquv) is the supreme ruling body of the Klingon Empire. The council meets at the Great Hall of the First City of the Klingon Empire on the planet Qo'noS (also known as Kronos in Federation standard). One of the writers responsible for Klingon background was Ronald D. Moore, who wrote famous Klingon episodes such as "Sins of the Father", where the Klingon High Council is first depicted in Star Trek. Later episodes and content in the franchise showed or referenced the High Council.
