Prussura IV was a planet, the fourth planet in the Prussura star system, one of only three class M planets in the Badlands, and the location of a Maquis colony in the early 2370s.

In 2376, the Federation starship USS Crockett was dispatched to find this colony. The colony was abandoned mid-use, as though the people had disappeared in a moment. (ST - New Worlds, New Civilizations short story: "The Specter of Jamestown")
