The Donatu system is a star system located on the edge of 23rd century Federation space, in the Beta Quadrant.

History and particularsEdit

The system is home to at least five planets, one of which (Donatu V) is Class M.

In the year 2244, the Donatu system was the location of the famous Battle of Donatu V between Starfleet and Klingon forces. (TOS episode: "The Trouble with Tribbles")

Mirror realityEdit

In the mirror universe's late 2240s or early 2250s, Donatu V was the site of a Klingon weapons test that destroyed the planet. Subsequently, the ISS Thermopylae and ISS Indomitable were engaged by the Klingons within the Donatu system. (Mirror Universe short story: "Ill Winds")
