Unnamed Gamma Quadrant nebulae
The following is a list of unnamed Gamma Quadrant nebulae.

Dominion staging area 
This nebula was located on the edge of Dominion space nearest to the Bajoran wormhole. Like another Gamma Quadrant nebula, the Chamra Vortex, this too contained pockets of Toh-maire gas. The composition of the nebula also interfered with the function of shields and sensors, but not tractor beams. 

In 2373, it served as a staging area for a large Dominion invasion fleet consisting of over fifty Dominion ships, including several Jem'Hadar battle cruisers and Jem'Hadar fighters, destined for the Alpha Quadrant. 

The invasion force was accidentally discovered by Worf and Elim Garak that year, when they took their runabout, the , through the nebula so as to be able to go deeper into Dominion space, while avoiding detection by the Jem'Hadar, and getting light years closer to the source of the transmission they were investigating. Garak originally discovered the nebula on a long range sensor scan. ()
