Tripoli IX is an inhabited planet located somewhere in the space of the Alpha or Beta Quadrants of the galaxy, the ninth planet in the Tripoli star system. This world was noted to be the origin of a specific piece of weapon platform technology, the Tripolian hellblazer. (TNG comic: "... Where No One Has Gone Before!")

Since advanced weaponry and technological equipment is identified as originating here, it can be determined that this is either the homeworld of a civilization that crafted the technology, or this world could be an outpost of a civilization that is responsible for this origination.
