Soukara was an inhabited planet in the Soukara system. During the Dominion War, this planet was in Dominion-controlled space and was the location for a Dominion base. The planet had at least two moons and a nearby asteroid field, which could be used to penetrate the Dominion sensor grid undetected. The base was located in the middle of a jungle, and was protected by transport inhibitors.
In 2374, Worf and Jadzia Dax were sent on a covert mission to Soukara to recover a Cardassian defector, Lasaran, who claimed to know the location and false identity of every Founder in the Alpha Quadrant. Unfortunately, Dax was severely injured by a Jem'Hadar patrol, and Worf chose to abort the mission to seek medical care for her. (DS9: "Change of Heart")
