Angoma was a planet located in the the galaxy's Alpha or Beta Quadrant. This homeworld of the ancient Angoman gorilla race was located in a sector containing several aggressive, warlike races, including the Mantis.
In 2266, Angoma was visited by the Federation starship USS Enterprise. James T. Kirk's landing party was similarly abducted, but the team was eventually rescued and returned to Angoma. During a celebration at a stadium afterward, some of the Enterprise crew played a game of soccer with the gorillas. (TOS comic: "Beware the Beast")
