A charged plasma field in or near the Bajoran system that hosts the Alpha Quadrant end of the Bajoran wormhole.

Though ships have always avoided it, a stranded Kai Taluno had first reported odd phenomenon there in the 22nd century; five of the nine known Bajoran orbs were found within it over the past 10,000 years, and 23 navigation reports of severe local neutrino disturbances are on record. In 2337, some 32 years before the Cardassian withdrawal from Bajor, it is also where Constable Odo was found. An extremely rare and violent plasma disruption in the belt circa stardate 47182.1 forced evacuation of nearby Deep Space Nine for all but a skeleton crew — when the Trill Verad tried to hijack the Dax symbiont.

The chance of sail damage from an ion storm while passing through the belt was one reason Chief O'Brien discounted the legendary solar-sail flight of an ancient Bajoran to Cardassia. But in recreating this mythical journey, Commander Sisko and his son Jake proved it could have occurred — it is believed that tachyon eddies in the Denorios Belt propelled the solar-sail vessel across interstellar distances at warp speed.
