The Separatist Council was a governing body, led by Count Dooku, within the Confederacy of Independent Systems. It was made up of a number of Separatist leaders from the various major powers that backed the Separatist cause during the Clone Wars, including the Trade Federation, the Techno Union, the Corporate Alliance, the Commerce Guild, and the InterGalactic Banking Clan. The entire Council was slaughtered by Darth Vader on Mustafar, bringing an end to the Clone Wars.
