Storage bay 3 was a storage bay on the USS Voyager which housed Neelix's pantry.

In 2373, Captain Kathryn Janeway told Neelix that she was planning on converting storage bay 3 into a containment chamber for sirillium, an energy source the crew had discovered in a class 17 nebula in the Delta Quadrant. Janeway told Neelix that he would have to make other arrangements to relocate his pantry. (VOY: "Flashback")
