The Draken system was an inhabited planetary system in the Taugan sector, near the Romulan Neutral Zone. The system consisted of the primary Draken and at least four planets, including Draken IV.

In 2257, during the first Federation-Klingon War, this system was occupied by the Klingons. (DIS: "The War Without, The War Within")

In the 2360s, Draken IV was home to a Starfleet base. (TNG: "Face of the Enemy")

This system was only mentioned in dialogue.
Draken, the system's primary, was located in the Beta Quadrant on a star chart seen in the Star Trek: Discovery episode "The War Without, The War Within".
According to Star Trek: Star Charts (p. 45) and Stellar Cartography: The Starfleet Reference Library ("Federation Historical Highlights, 2161-2385"), in the distant past, about 2,000 years ago, this system was a destination on the Debrune trade route.
