Goran IV was a planet in or near Federation space in the Beta Quadrant. Goran IV was the fourth planet in the Goran system, and was home to a pre-industrial Goranian civilization, with a population of approximately 1.1 billion.
In 2274, a probe used to monitor the Klingon Neutral Zone crashed on the planet at some point prior to stardate 8124.5, releasing toxic gas into the atmosphere. The USS Enterprise was diverted to make sure the gas did not harm anyone. (TOS comic: "The Long Night's Dawn!")
